Income Tax Disclosure [Abstract]
Income Taxes	NOTE 7 — Income Taxes The Company’s tax provision for interim periods is determined using an estimate of its annual effective income tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates its estimated annual effective income tax rate, and if the estimated income tax rate changes, a cumulative adjustment is made. The effective income tax rates for the first three months of 2017 and 2016 were 31.8% and 37.2%, respectively. The Company recognizes accrued interest and penalties related to uncertain tax positions in income tax expense. It is reasonably possible that, within the next twelve months, the amount of gross unrecognized tax benefits could be reduced by approximately $1.4 million as a result of the closure of tax statutes related to existing uncertain tax positions.

The foreign net operating loss carryforward is $22.1 million , of which $5.5 million expires between 2017 and 2036 and the remainder has no expiration date. The Company has a tax benefit from a state net operating loss carryforward of $2.7 million that expires between 2017 and 2036 . The Company also has a tax benefit from a non-consolidated As of December 31, 2016 and 2015 , the Company was not in a cumulative three -year loss position and it was determined that it was more likely than not that its U.S. deferred tax assets will be realized. As of December 31, 2014, the Company reversed a valuation allowance of $1.3 million against its state net operating loss carryforward. As of December 31, 2016 and 2015 , the Company recorded valuation allowances of $4.5 million and $4.2 million , respectively, against certain foreign net deferred tax assets. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income (including reversals of deferred tax liabilities). The Company reviews all valuation allowances related to deferred tax assets and will reverse these valuation allowances, partially or totally, when appropriate under ASC 740. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: 2016 2015 2014 (In millions) Unrecognized Tax Benefit — January 1, $ 6.3 $ 6.5 $ 5.9 Gross Increases to Tax Positions Related to Prior Years 0.3 0.3 0.8 Gross Decreases to Tax Positions Related to Prior Years — (0.1 ) (0.2 ) Expiration of Statute of Limitations (3.7 ) (0.4 ) — Unrecognized Tax Benefit — December 31, $ 2.9 $ 6.3 $ 6.5 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $2.4 million at December 31, 2016 and $5.5 million at December 31, 2015. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. During the year ended December 31, 2016 and 2015, the Company recognized approximately $(1.4) million and $0.2 million , respectively, in net interest and penalties. The Company had approximately $0.4 million and $1.9 million for the payment of interest and penalties accrued at December 31, 2016 and 2015, respectively. It is reasonably possible that within the next twelve months the amount of gross unrecognized tax benefits could be reduced by approximately $1.4 million as a result of the closure of tax statutes related to existing uncertain tax positions. The Company is subject to taxation in the U.S. and various state and foreign jurisdictions. The Company’s tax years for 2013 through 2016 remain open for examination by the Internal Revenue Service and 2012 through 2016 remain open for examination by various state and foreign taxing authorities. Deferred taxes have not been provided on approximately $131.1 million of undistributed earnings of the Company’s foreign subsidiaries as it is the Company’s policy and intent to permanently reinvest such earnings. The Company has determined that it is not practicable to determine the unrecognized tax liability on such undistributed earnings.

Commitments and Contingencies Disclosure [Abstract]
Commitments, Contingencies and Litigation Judgment	NOTE 10 — Commitments, Contingencies and Litigation Settlement The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. The Company records a liability for loss contingencies in the consolidated financial statements when a loss is known or considered probable and the amount can be reasonably estimated. Our provisions are based on historical experience, current information and legal advice, and they may be adjusted in the future based on new developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments and potential actions by third parties. Although it is not possible to predict with certainty the ultimate outcome or cost of these matters, the Company believes they will not have a material adverse effect on our consolidated financial statements. IPSCO Tubulars Inc. d/b/a TMK IPSCO sued Ajax Tocco Magnethermic Corporation (“ATM”), a subsidiary of the Company, in the United States District Court for the Eastern District of Arkansas claiming that equipment supplied by ATM for heat treating certain steel pipe at IPSCO’s Blytheville, Arkansas facility did not perform as required by the contract. The complaint alleged causes of action for breach of contract, gross negligence and constructive fraud. IPSCO sought approximately $10.0 million in damages plus an unspecified amount of punitive damages. In September 2013, the district court issued a judgment in favor of IPSCO in the amount of $5.2 million , which the Company recognized and accrued for at that time. In March 2016, the district court issued an order granting, in part, IPSCO’s motion for fees and costs and awarding $2.2 million to IPSCO, which the Company accrued for as of December 31, 2015. ATM filed a third appeal of that decision. On March 28, 2017, the Company and IPSCO agreed to a settlement and release of all claims for the payment by the Company of $4.0 million to IPSCO, which was made in March 2017. As of the settlement date, the Company had $7.3 million accrued for this matter. The Company reversed the excess liability and recognized $3.3 million in income in the first quarter of 2017. Our subsidiaries are involved in a number of contractual and warranty related disputes. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates. In August 2013, the Company received a subpoena from the staff of the Securities and Exchange Commission (“SEC”) in connection with the staff’s investigation of a third party. At that time, the Company also learned that the U.S. Department of Justice (“DOJ”) is conducting a criminal investigation of the third party. In connection with its initial response to the staff’s subpoena, the Company disclosed to the staff of the SEC that, in November 2007, the third party participated in a payment on behalf of the Company to a foreign tax official that implicates the Foreign Corrupt Practices Act. The Board of Directors formed a special committee to review the Company’s transactions with the third party and to make any recommendations to the Board of Directors with respect thereto. The Company intends to cooperate fully with the SEC and the DOJ in connection with their investigations of the third party and with the SEC in light of the Company’s disclosure. The Company is unable to predict the outcome or impact of the special committee’s investigation or the length, scope or results of the SEC’s review or the impact on its results of operations.	NOTE 9 — Commitments, Contingencies and Litigation Judgment The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. Although the Company cannot precisely predict the amount of any liability that may ultimately arise with respect to any of these matters, the Company records provisions when it considers the liability probable and reasonably estimable. Our provisions are based on historical experience and legal advice, reviewed quarterly and adjusted according to developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments about potential actions by third parties, such as regulators, courts, and state and federal legislatures. Changes in the amounts of our loss provisions, which can be material, affect our financial condition. Due to the inherent uncertainties in the process undertaken to estimate potential losses, we are unable to estimate an additional range of loss in excess of our accruals. While it is reasonably possible that such excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that such excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position. Our subsidiaries are involved in a number of contractual and warranty related disputes. At this time, we cannot reasonably determine the probability of a loss, and the timing and amount of loss, if any, cannot be reasonably estimated. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates. IPSCO Tubulars Inc. d/b/a TMK IPSCO sued Ajax Tocco Magnethermic Corporation (“ATM”), a subsidiary of Industries, in the United States District Court for the Eastern District of Arkansas claiming that equipment supplied by ATM for heat treating certain steel pipe at IPSCO’s Blytheville, Arkansas facility did not perform as required by the contract. The complaint alleged causes of action for breach of contract, gross negligence and constructive fraud. IPSCO sought approximately $10 million in damages plus an unspecified amount of punitive damages. ATM denied the allegations. ATM subsequently obtained summary judgment on the constructive fraud claim, which was dismissed by the district court prior to trial. The remaining claims were the subject of a bench trial that occurred in May 2013. After IPSCO presented its case, the district court entered partial judgment in favor of ATM, dismissing the gross negligence claim, a portion of the breach of contract claim, and any claim for punitive damages. The trial proceeded with respect to the remainder of IPSCO’s claim for breach of contract. In September 2013, the district court issued a judgment in favor of IPSCO in the amount of $5.2 million, which the Company recognized and accrued for at that time. IPSCO subsequently filed a motion seeking to recover $3.8 million in attorneys’ fees and costs. The district court reserved ruling on that issue pending an appeal. In October 2013, ATM filed an appeal with the U.S. Court of Appeals for the Eighth Circuit seeking reversal of the judgment in favor of IPSCO. In November 2013, IPSCO filed a cross-appeal seeking reversal of the dismissal of its claim for gross negligence and punitive damages. The Eighth Circuit issued an opinion in March 2015 affirming in part, reversing in part, and remanding the case. It affirmed the district court’s determination that ATM was liable for breach of contract. It also affirmed the district court’s dismissal of IPSCO’s claim for gross negligence and punitive damages. However, the Eighth Circuit reversed nearly all of the damages awarded by the district court and remanded for further findings on the issue of damages, including whether consequential damages are barred under the express language of the contract. Because IPSCO did not appeal the award of $5.2 million in its favor, those damages could be decreased, but could not be increased, on remand. On remand, the district court entered an order once again awarding IPSCO $5.2 million . In December 2015, ATM filed a second appeal with the Eighth Circuit seeking reversal of the damages award. That appeal is pending. In March 2016, the district court issued an order granting, in part, IPSCO’s motion for fees and costs and awarding $2.2 million to IPSCO, which the Company accrued for as of December 31, 2015. ATM filed a third appeal of that decision. As of December 31, 2016, the Company had $7.4 million accrued for this matter. In August 2013, we received a subpoena from the staff of the SEC in connection with the staff’s investigation of a third party. At that time, we also learned that the Department of Justice (“DOJ”) is conducting a criminal investigation of the third party. In connection with its initial response to the staff’s subpoena, we disclosed to the staff of the SEC that, in November 2007, the third party participated in a payment on behalf of us to a foreign tax official that implicates the Foreign Corrupt Practices Act. The Board of Directors formed a special committee to review our transactions with the third party and to make any recommendations to the Board of Directors with respect thereto. The Company intends to cooperate fully with the SEC and the DOJ in connection with their investigations of the third party and with the SEC in light of the Company’s disclosure. The Company is unable to predict the outcome or impact of the special committee’s investigation or the length, scope or results of the SEC’s review or the impact on its results of operations.

In addition, the Company has an unfunded postretirement benefit plan. One of its defined benefit plans, covering most U.S. employees not covered by collective bargaining agreements, utilizes a cash balance formula. Under a cash balance formula, a plan participant accumulates a retirement benefit consisting of pay credits that are based upon a percentage of current eligible earnings and current interest credits. For the remaining defined benefit plans, benefits are based on the employee’s years of service. For the defined contribution plans, the costs charged to operations and the amount funded are based upon a percentage of the covered employees’ compensation. The Company’s objective for the pension plan is to monitor the funded ratio; create general investment goals in regards to acceptable risk and liquidity needs ensuring the long-term interests of participants and beneficiaries are considered and manage risk by minimizing the short-term and long-term risk of actual expenses and contribution requirements. The following tables set forth the changes in benefit obligation, plan assets, funded status and amounts recognized in the consolidated balance sheet for the defined benefit pension and postretirement benefit plans as of December 31, 2016 and 2015: Pension Benefits Postretirement Benefits 2016 2015 2016 2015 (In millions) Change in benefit obligation Benefit obligation at beginning of year $ 58.4 $ 61.1 $ 13.5 $ 17.0 Service cost 2.4 2.6 — — Interest cost 1.8 2.3 0.3 0.5 Actuarial losses (gains) 0.5 (3.0 ) (2.6 ) (2.7 ) Benefits and expenses paid, net of contributions (4.6 ) (4.6 ) (1.2 ) (1.3 ) Benefit obligation at end of year $ 58.5 $ 58.4 $ 10.0 $ 13.5 Change in plan assets Fair value of plan assets at beginning of year $ 117.3 $ 125.7 $ — $ — Actual return on plan assets 8.3 (2.9 ) — — Company contributions — — 1.2 1.3 Cash transfer to fund postretirement benefit payments (0.8 ) (0.9 ) — — Benefits and expenses paid, net of contributions (4.6 ) (4.6 ) (1.2 ) (1.3 ) Fair value of plan assets at end of year $ 120.2 $ 117.3 $ — $ — Funded (underfunded) status of the plans $ 61.7 $ 58.9 $ (10.0 ) $ (13.5 ) Amounts recognized in the consolidated balance sheets consist of: Pension Benefits Postretirement Benefits 2016 2015 2016 2015 (In millions) Pension assets $ 61.7 $ 58.9 $ — $ — Other current liabilities — — 1.2 1.4 Other long-term liabilities — — 8.8 12.1 $ 61.7 $ 58.9 $ 10.0 $ 13.5 Amounts recognized in Accumulated other comprehensive loss Net actuarial loss $ 25.8 $ 25.2 $ 1.7 $ 4.4 Net prior service cost (credit) 0.3 0.3 (0.2 ) (0.3 ) Accumulated other comprehensive loss $ 26.1 $ 25.5 $ 1.5 $ 4.1 The pension plan weighted-average asset allocation at December 31, 2016 and 2015 and target allocation for 2017 are as follows: Plan Assets Target 2017 2016 2015 Asset Category Equity securities 45-75 % 61.9 % 62.7 % Debt securities 20-40 % 24.6 % 25.4 % Other 0-20 % 13.5 % 11.9 % 100 % 100 % 100 % The following table sets forth, by level within the fair value hierarchy, the pension plans assets: 2016 2015 Level 1 Total (at Fair Value) Level 1 Total (at Fair Value) (In millions) Common stock $ 40.0 $ 40.0 $ 38.3 $ 38.3 Equity Funds 29.0 29.0 29.1 29.1 Foreign Stock 5.4 5.4 5.7 5.7 U.S. Government obligations 8.1 8.1 7.4 7.4 Fixed income funds 14.1 14.1 14.6 14.6 Corporate Bonds 6.3 6.3 6.8 6.8 Cash and Cash Equivalents 3.3 3.3 1.2 1.2 Total $ 106.2 $ 103.1 Investments measured at net asset value: Common collective trust 1.1 1.5 Hedge funds 12.9 12.7 Total assets at fair value $ 120.2 $ 117.3 The following tables summarize the assumptions used in the valuation of pension and postretirement benefit obligations at December 31, and the measurement of the net periodic benefit cost in the following year.

This assumption was supported by the asset return generation model, which projected future asset returns using simulation and asset class correlation. Effective December 31, 2015, the Company adopted a change in the method used to estimate the service and interest cost components of net periodic benefit cost for its defined benefit pension plans. Historically, the service and interest cost components were estimated using a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. For 2016, the Company used a spot rate approach by applying the specific spot rates along the yield curve to the relevant projected cash flows in the estimation of the service and interest components of benefit cost, resulting in a more precise measurement. These spot rates were determined as of the measurement date of December 31, 2015. This change does not affect the measurement of total benefit obligations. The change was accounted for as a change in estimate and, accordingly, was accounted for prospectively starting in 2016. The spot rates used to determine service and interest costs ranged from 3.29% to 4.19% for the U.S. pension plan. The reductions in service and interest costs for 2016 associated with this change were $0.1 million and $0.5 million , respectively. Similar to the changes in the discount rate approach discussed for the pension plans above, effective December 31, 2015, we elected to use an approach that discounts the individual expected cash flows underlying interest and service costs using the applicable spot rates derived from the yield curve used to determine the benefit obligation to the relevant projected cash flows. The spot rates used to determine service and interest costs ranged from 2.93% to 4.43% for the postretirement benefit plans. The reductions in service and interest costs in 2016 associated with this change were $0.0 million and $0.1 million, respectively.

The estimated net loss and prior service cost for the postretirement plans that will be amortized from accumulated other comprehensive income into net periodic benefit cost over the year ending December 31, 2017 is less than $ 0.1 million.

In January 2008, a Supplemental Executive Retirement Plan (“SERP”) for the Company’s Chairman and Chief Executive Officer (“CEO”) was approved by the Compensation Committee of the Board of Directors of the Company. The SERP provides an annual supplemental retirement benefit for up to $0.4 million upon the CEO’s termination of employment with the Company. The vested retirement benefit will be equal to a percentage of the SERP that is equal to the ratio of (1) his credited service with the Company prior to January 1, 2008 (up to a maximum of thirteen years), plus his credited service after January 1, 2008 (up to a maximum of seven years) to (2) twenty years of credited service. In the event of a change in control before the CEO’s termination of employment, he will receive 100% of the SERP. The Company recorded income of $0.2 million in 2016 , and expense of $0.6 million in 2015 and $0.5 million in 2014 related to the SERP.

Asset Impairment	NOTE 13 — Asset Impairment In the first quarter of 2016, due to the accelerated end of production in certain programs with an automotive customer, the Company evaluated its long-lived assets in accordance with ASU 360, “Property, Plant and Equipment.” As the carrying value of the assets exceeded the expected undiscounted cash flows, the Company estimated the fair value of these assets to determine whether impairment existed. The fair value of the assets was estimated, using Level 2 inputs, based on the expected sale proceeds of similar machinery and equipment as determined using third party quotes and appraisals. As a result of its analysis, the Company recorded an asset impairment charge of $4.0 million.

Accounting Estimates	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.	Accounting Estimates:
Cash Equivalents		Cash Equivalents:
Inventories		Inventories: first-in, first-out
Property, Plant and Equipment		Property, Plant and Equipment:
Impairment of Long-Lived Assets		Impairment of Long-Lived Assets:
Goodwill and Indefinite-Lived Assets		Goodwill and Indefinite-Lived Assets: Intangibles — Goodwill and Other .
Fair Values of Financial Instruments		Fair Values of Financial Instruments: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Changes in assumptions or estimation methods could affect the fair value estimates; however, we do not believe any such changes would have a material impact on our financial condition, results of operations or cash flows. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and borrowings under the Credit Agreement (as defined in Note 6) approximate fair value at December 31, 2016 and December 31, 2015 because of the short-term nature of these instruments. The fair values of long-term debt and pension plan assets are disclosed in Note 6 and Note 11, respectively. The Company has not changed its valuation techniques for measuring fair value during 2016 , and there were no transfers between levels during the periods presented.
Income Taxes	The Company’s tax provision for interim periods is determined using an estimate of its annual effective income tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter, the Company updates its estimated annual effective income tax rate, and if the estimated income tax rate changes, a cumulative adjustment is made.	Income Taxes:

Commitments and Contingencies	The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. The Company records a liability for loss contingencies in the consolidated financial statements when a loss is known or considered probable and the amount can be reasonably estimated. Our provisions are based on historical experience, current information and legal advice, and they may be adjusted in the future based on new developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments and potential actions by third parties. Although it is not possible to predict with certainty the ultimate outcome or cost of these matters, the Company believes they will not have a material adverse effect on our consolidated financial statements.	The Company is subject to various pending and threatened legal proceedings arising in the ordinary course of business. Although the Company cannot precisely predict the amount of any liability that may ultimately arise with respect to any of these matters, the Company records provisions when it considers the liability probable and reasonably estimable. Our provisions are based on historical experience and legal advice, reviewed quarterly and adjusted according to developments. Estimating probable losses requires the analysis of multiple forecasted factors that often depend on judgments about potential actions by third parties, such as regulators, courts, and state and federal legislatures. Changes in the amounts of our loss provisions, which can be material, affect our financial condition. Due to the inherent uncertainties in the process undertaken to estimate potential losses, we are unable to estimate an additional range of loss in excess of our accruals. While it is reasonably possible that such excess liabilities, if they were to occur, could be material to operating results in any given quarter or year of their recognition, we do not believe that it is reasonably possible that such excess liabilities would have a material adverse effect on our long-term results of operations, liquidity or consolidated financial position. Our subsidiaries are involved in a number of contractual and warranty related disputes. At this time, we cannot reasonably determine the probability of a loss, and the timing and amount of loss, if any, cannot be reasonably estimated. We believe that appropriate liabilities for these contingencies have been recorded; however, actual results may differ materially from our estimates.
Basis of Presentation	The condensed consolidated financial statements include the accounts of Park-Ohio Industries, Inc. and its subsidiaries (collectively, “we”, “our” or the “Company”).
