Basis of Presentation	'
	Basis of Presentation
	The condensed consolidated financial statements include the accounts of Park-Ohio Industries, Inc. and its subsidiaries (collectively, “we” or the “Company”). All significant intercompany transactions have been eliminated in consolidation. Park-Ohio Industries, Inc. is a wholly-owned subsidiary of Park-Ohio Holdings Corp. (“Holdings”). Certain amounts in the prior years’ financial statements have been reclassified to conform to the current year presentation.
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three-month period ended March 31, 2014 are not necessarily indicative of the results that may be expected for the year ending December 31, 2014. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	On September 3, 2013, we sold all of the outstanding equity interests of a non-core business unit in the Supply Technologies segment. This business unit is a provider of high-quality machine to machine information technology solutions, products and services. The results of the business unit have been reported as discontinued operations in the financial statements.

	Accounting Pronouncements Adopted
	In February 2013, the FASB issued ASU 2013-04, “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date,” which requires entities to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors plus additional amounts the reporting entity expects to pay on behalf of its co-obligors. Entities are also required to disclose the nature and amount of the obligation as well as other information about those obligations. This ASU is effective prospectively for reporting periods beginning after December 15, 2013. The adoption of this ASU has not had a material effect on our consolidated financial statements as it aligns with our current presentation.
	In February 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” requiring reporting entities that no longer have a controlling financial interest in a subsidiary or group of assets that is considered a business within a foreign entity, to release the cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. For equity method investments that are foreign entities, the partial sale requires a pro rata portion of the cumulative translation adjustment to be released into net income upon a partial sale of such an equity investment. However, for an equity method investment that is not a foreign entity, the release of the cumulative translation adjustment into net income is required only if the partial sale represents a complete or substantially complete liquidation of the foreign entity that contains the equity method investment. Additionally, the amendments in this update clarify that the sale of an investment in a foreign entity requiring release into net income the cumulative translation adjustment upon the occurrence of events that includes (1) events that result in the loss of a controlling financial interest in a foreign entity and (2) events that result in an acquirer obtaining control of an acquiree in which it held an equity interest immediately before the acquisition date. This ASU is effective prospectively for reporting periods beginning after December 15, 2013. The adoption of this ASU has not had a material effect on our consolidated financial statements as it aligns with our current presentation.
	Recent Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which raises the threshold for disposals to qualify as discontinued operations and requires new disclosures for discontinued operations and for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective prospectively for reporting periods beginning with the first quarter of 2015. The Company is currently evaluating the impact of adopting this guidance.

	Segments
	The Company operates through three reportable segments: Supply Technologies, Assembly Components and Engineered Products. Supply Technologies provides our customers with Total Supply Management™ services for a broad range of high-volume, specialty production components. Total Supply Management™ manages the efficiencies of every aspect of supplying production parts and materials to our customers’ manufacturing floor, from strategic planning to program implementation, and includes such services as engineering and design support, part usage and cost analysis, supplier selection, quality assurance, bar coding, product packaging and tracking, just-in-time and point-of-use delivery, electronic billing services and ongoing technical support. Assembly Components manufactures cast aluminum components, automotive and industrial rubber and thermoplastic products, fuel filler and hydraulic assemblies for automotive, agricultural equipment, construction equipment, heavy-duty truck and marine equipment industries. Assembly Components also provides value-added services such as design and engineering, machining and assembly. Engineered Products operates a diverse group of niche manufacturing businesses that design and manufacture a broad range of high quality products engineered for specific customer applications.
	The Company primarily evaluates performance and allocates resources based on segment operating income as well as projected future performance.

	Financing Arrangements
	The Company is a party to a credit and security agreement, dated November 5, 2003, as amended (the “Credit Agreement”), with a group of banks, under which it may borrow or issue standby letters of credit or commercial letters of credit. On March 23, 2012, the Credit Agreement was amended and restated to, among other things, increase the revolving loan commitment from $200.0 million to $220.0 million, and provide a term loan for $25.0 million that is secured by certain real estate and machinery and equipment. Amounts borrowed under the revolving credit facility may be borrowed at either (i) LIBOR plus 1.75% to 2.75% or (ii) the bank’s prime lending rate minus 0.25% to 1.00%, at the Company’s election. The LIBOR-based interest rate is dependent on the Company’s debt service coverage ratio, as defined in the Credit Agreement. Under the Credit Agreement, a detailed borrowing base formula provides borrowing availability to the Company based on percentages of eligible accounts receivable and inventory. On April 3, 2013, the Credit Agreement was amended to increase the advance rate on eligible accounts receivable and inventory. The interest rate on the revolving credit facility was 1.94% at March 31, 2014. Interest on the term loan is at either (i) LIBOR plus 2.75% or (ii) the bank’s prime lending rate plus 0.25%, at the Company’s election. The term loan is amortized based on a seven-year schedule with the balance due at maturity (April 7, 2016). The interest rate on the term loan was 3.00% at March 31, 2014.

	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.
	Ajax Tocco Magnethermic Corporation (“ATM”) was the defendant in a lawsuit in the United States District Court for the Eastern District of Arkansas. The plaintiff is IPSCO Tubulars Inc. d/b/a TMK IPSCO. The complaint alleged claims for breach of contract, gross negligence and constructive fraud, and TMK IPSCO sought approximately $6.0 million in direct and $4.0 million in consequential damages as well as an unspecified amount of punitive damages. ATM denied the allegations against it, believes it has a number of meritorious defenses and vigorously defended the lawsuit. A motion for partial summary judgment filed by ATM that, among other things, denied the plaintiff's fraud claims was granted by the district court. The remaining claims were the subject of a bench trial in May 2013. At the close of TMK IPSCO's case, the court entered partial judgment in favor of ATM, dismissing the gross negligence claim, dismissing a portion of the breach of contract claim, and dismissing any claim for punitive damages. The trial proceeded with respect to the remainder of TMK IPSCO's claim for damages and, in September 2013, the district court awarded TMK IPSCO damages of approximately $5.2 million. ATM is appealing the court’s decision. TMK IPSCO is also appealing the decision and, additionally, it has asked the court for $3.8 million in attorney's fees.
	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 responding 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 of the Company has 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.

Supplemental Guarantor Information	'
	Supplemental Guarantor Information
	Each of the material domestic direct and indirect wholly-owned subsidiaries of the Company (the “Guarantor Subsidiaries”) has fully and unconditionally guaranteed, on a joint and several basis, to pay principal, premium, and interest with respect to the Company's 8.125% Senior Notes due 2021. Each of the Guarantor Subsidiaries is “100% owned,” as defined by Rule 3-10(h)(1) of Regulation S-X.
	The guarantee of a Guarantor Subsidiary will automatically terminate, and the obligations of such Guarantor Subsidiary under its guarantee of 8.125% Senior Notes due 2021 will be released:
	(a) in the event of any sale or other disposition of all or substantially all of the assets or all of the capital stock of any Subsidiary Guarantor, by way of merger, consolidation or otherwise;
	(b) upon designation of any Subsidiary Guarantor as an “unrestricted subsidiary” (as defined in the indenture governing the 8.125% Senior Notes due 2021 (the “Indenture”);
	(c) upon defeasance or satisfaction and discharge of the Indenture; and
	(d) upon the release of such Subsidiary Guarantor's guarantees under all credit facilities of the Company (other than a release as a result of payment under or a discharge of such guarantee).
	Effective in the third quarter of 2013, Southwest Steel Processing LLC (“SSC”) was released from its guarantee of the 8.125% Senior Notes due 2021 in conjunction with its designation as an "Unrestricted Subsidiary" under the Indenture and the sale of 25% of its business. During the third quarter of 2013, all the outstanding equity interests of a non-core business unit in the Supply Technologies segment was sold and released as a guarantor of the Company's 8.125% Senior Notes due 2021 under customary conditions. As a result of the aforementioned releases from the guarantee to the Company's 8.125% Senior Notes due 2021 all periods presented have been restated to reflect SSP and the disposed Supply Technologies business unit as non-guarantor subsidiaries.

Accounting Changes and Error Corrections [Abstract]	'

	Accounting Pronouncements Adopted
	In February 2013, the FASB issued ASU 2013-04, “Obligations Resulting from Joint and Several Liability Arrangements for Which the Total Amount of the Obligation is Fixed at the Reporting Date,” which requires entities to measure obligations resulting from joint and several liability arrangements for which the total amount of the obligation is fixed at the reporting date, as the sum of the amount the reporting entity agreed to pay on the basis of its arrangement among its co-obligors plus additional amounts the reporting entity expects to pay on behalf of its co-obligors. Entities are also required to disclose the nature and amount of the obligation as well as other information about those obligations. This ASU is effective prospectively for reporting periods beginning after December 15, 2013. The adoption of this ASU has not had a material effect on our consolidated financial statements as it aligns with our current presentation.
	In February 2013, the FASB issued ASU 2013-05, “Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity,” requiring reporting entities that no longer have a controlling financial interest in a subsidiary or group of assets that is considered a business within a foreign entity, to release the cumulative translation adjustment into net income only if the sale or transfer results in the complete or substantially complete liquidation of the foreign entity in which the subsidiary or group of assets had resided. For equity method investments that are foreign entities, the partial sale requires a pro rata portion of the cumulative translation adjustment to be released into net income upon a partial sale of such an equity investment. However, for an equity method investment that is not a foreign entity, the release of the cumulative translation adjustment into net income is required only if the partial sale represents a complete or substantially complete liquidation of the foreign entity that contains the equity method investment. Additionally, the amendments in this update clarify that the sale of an investment in a foreign entity requiring release into net income the cumulative translation adjustment upon the occurrence of events that includes (1) events that result in the loss of a controlling financial interest in a foreign entity and (2) events that result in an acquirer obtaining control of an acquiree in which it held an equity interest immediately before the acquisition date. This ASU is effective prospectively for reporting periods beginning after December 15, 2013. The adoption of this ASU has not had a material effect on our consolidated financial statements as it aligns with our current presentation.
	Recent Accounting Pronouncements Not Yet Adopted
	In April 2014, the FASB issued ASU 2014-08, "Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity," which raises the threshold for disposals to qualify as discontinued operations and requires new disclosures for discontinued operations and for individually material disposal transactions that do not meet the definition of a discontinued operation. The ASU is effective prospectively for reporting periods beginning with the first quarter of 2015. The Company is currently evaluating the impact of adopting this guidance.
