Accounting Policies [Abstract]
Summary of Accounting Policies	Note 1: Summary of Accounting Policies Principles of consolidation and presentation The Condensed Consolidated Financial Statements include the accounts of Snap-on “Snap-on” Snap-on’s 10-K Snap-on Snap-on Snap-on’s In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the Condensed Consolidated Financial Statements for the three and nine month periods ended September 30, 2017, and October 1, 2016, have been made. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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. Financial Instruments The fair value of the company’s derivative financial instruments is generally determined using quoted prices in active markets for similar assets and liabilities. The carrying value of the company’s non-derivative New Accounting Standards The following new accounting pronouncement was adopted in fiscal year 2017: In January 2017, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment value. Snap-on The following new accounting pronouncements, and related impacts on adoption, are being evaluated by the company: In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities No. 2017-12 In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost non-service-cost The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods; early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The amendments in this ASU are to be applied retrospectively. The company does not expect the adoption of this ASU to have a significant impact on its consolidated income statement. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other Than Inventory In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) No. 2016-13 In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) No. 2016-02 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Entities have the option of adopting this standard using either a full retrospective approach or a modified retrospective approach (i.e., through a cumulative-effect adjustment directly to retained earnings at the time of adoption). Snap-on As of September 30, 2017, and subject to the company’s ongoing evaluation of new transactions and contracts, the company has substantially completed its evaluation of the expected impact of adopting Topic 606 and anticipates that the adoption of this standard will not have a significant impact on the company’s consolidated financial statements. The company believes that the adoption will result in the recognition of an inventory asset related to certain product returns by increasing the returns liability and an inventory asset for the anticipated value of the returns; the corresponding increase in the inventory asset and returns liability is expected to be in the range of $24 million to $28 million at the date of adoption. The adoption will also result in the recognition of an increase in the inventory obsolescence reserve related to the anticipated value on returns in the range of $2 million to $3 million with a corresponding adjustment to beginning retained earnings. The company expects to adopt Topic 606 at the beginning of its 2018 fiscal year using the modified retrospective approach.

Receivable balances are considered delinquent when contractual payments become 30 days past due. Finance receivables are generally placed on nonaccrual status (nonaccrual of interest and other fees): (i) when a customer is placed on repossession status; (ii) upon receipt of notification of bankruptcy; (iii) upon notification of the death of a customer; or (iv) in other instances in which management concludes collectability is not reasonably assured. Finance receivables that are considered nonperforming include receivables that are on nonaccrual status and receivables that are generally more than 90 days past due. Contract receivables are generally placed on nonaccrual status: (i) when a receivable is more than 90 days past due or at the point a customer’s account is placed on terminated status regardless of its delinquency status; (ii) upon notification of the death of a customer; or (iii) in other instances in which management concludes collectability is not reasonably assured. Contract receivables that are considered nonperforming include receivables that are on nonaccrual status and receivables that are generally more than 90 days past due. The accrual of interest and other fees is resumed when the finance or contract receivable becomes contractually current and collection of all remaining contractual amounts due is reasonably assured. Finance and contract receivables are evaluated for impairment on a collective basis. A receivable is impaired when it is probable that all amounts related to the receivable will not be collected according to the contractual terms of the applicable agreement. Impaired finance and contract receivables are covered by the company’s respective allowances for doubtful accounts and are charged-off It is the general practice of Snap-on’s Snap-on’s The aging of finance and contract receivables as of September 30, 2017, and December 31, 2016, is as follows: (Amounts in millions) 30-59 Days Past 60-90 Greater Total Past Total Not Total Greater September 30, 2017: Finance receivables $ 16.0 $ 11.6 $ 19.3 $ 46.9 $ 1,531.6 $ 1,578.5 $ 15.1 Contract receivables 1.4 0.7 1.7 3.8 411.6 415.4 0.8 December 31, 2016: Finance receivables $ 15.1 $ 9.8 $ 17.0 $ 41.9 $ 1,413.7 $ 1,455.6 $ 13.2 Contract receivables 1.4 0.9 1.4 3.7 375.0 378.7 0.5 The amount of performing and nonperforming finance and contract receivables based on payment activity as of September 30, 2017, and December 31, 2016, is as follows: September 30, 2017 December 31, 2016 (Amounts in millions) Finance Contract Finance Contract Performing $ 1,550.7 $ 413.2 $ 1,430.7 $ 376.7 Nonperforming 27.8 2.2 24.9 2.0 Total $ 1,578.5 $ 415.4 $ 1,455.6 $ 378.7 The amount of finance and contract receivables on nonaccrual status as of September 30, 2017, and December 31, 2016, is as follows: (Amounts in millions) September 30, December 31, Finance receivables $ 12.7 $ 11.7 Contract receivables 1.5 1.5 The following is a rollforward of the allowances for doubtful accounts for finance and contract receivables for the three and nine months ended September 30, 2017: Three Months Ended September 30, 2017 Nine Months Ended September 30, 2017 (Amounts in millions) Finance Contract Finance Contract Allowances for doubtful accounts: Beginning of period $ 52.5 $ 4.8 $ 48.6 $ 3.9 Provision 12.8 0.8 38.6 2.7 Charge-offs (12.6) (0.7) (38.0) (1.9) Recoveries 1.5 0.2 4.9 0.3 Currency translation – – 0.1 0.1 End of period $ 54.2 $ 5.1 $ 54.2 $ 5.1 The following is a rollforward of the allowances for doubtful accounts for finance and contract receivables for the three and nine months ended October 1, 2016: Three Months Ended October 1, 2016 Nine Months Ended October 1, 2016 (Amounts in millions) Finance Contract Finance Contract Allowances for doubtful accounts: Beginning of period $ 42.6 $ 4.5 $ 38.2 $ 4.4 Provision 10.8 0.5 30.4 1.1 Charge-offs (9.2) (0.6) (28.0) (1.3) Recoveries 1.4 0.1 5.0 0.3 End of period $ 45.6 $ 4.5 $ 45.6 $ 4.5

Financial Instruments	Note 9: Financial Instruments Derivatives: The criteria used to determine if hedge accounting treatment is appropriate are: (i) the designation of the hedge to an underlying exposure; (ii) whether or not overall risk is being reduced; and (iii) if there is a correlation between the value of the derivative instrument and the underlying hedged item. On the date a derivative contract is entered into, Snap-on Snap-on The company is exposed to global market risks, including the effects of changes in foreign currency exchange rates, interest rates, and the company’s stock price, and therefore uses derivatives to manage financial exposures that occur in the normal course of business. The primary risks managed by using derivative instruments are foreign currency risk, interest rate risk and stock-based deferred compensation risk.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between participants at the measurement date. Level 2 fair value measurements for derivative assets and liabilities are measured using quoted prices in active markets for similar assets and liabilities.

The fair value estimates of finance and contract receivables are derived utilizing discounted cash flow analyses performed on groupings of receivables that are similar in terms of loan type and characteristics. The cash flow analyses consider recent prepayment trends where applicable. The cash flows are discounted over the average life of the receivables using a current market discount rate of a similar term adjusted for credit quality. Significant inputs to the fair value measurements of the receivables are unobservable and, as such, are classified as Level 3. • Fair value of long-term debt and current maturities of long-term debt was estimated, using Level 2 fair value measurements, based on quoted market values of Snap-on’s • The fair value of all other financial instruments, including trade and other accounts receivable, accounts payable and other financial instruments, approximates such instruments’ carrying value due to their short-term nature.

Stock-based Compensation and Other Stock Plans	Note 12: Stock-based Compensation and Other Stock Plans The 2011 Incentive Stock and Awards Plan (the “2011 Plan”) provides for the grant of stock options, performance awards, stock appreciation rights (“SARs”) and restricted stock awards (which may be designated as “restricted stock units” or “RSUs”). No further grants are being made under its predecessor, the 2001 Incentive Stock and Awards Plan (the “2001 Plan”), although outstanding awards under the 2001 Plan will continue in accordance with their terms. As of September 30, 2017, the 2011 Plan had 3,287,403 shares available for future grants. The company uses treasury stock to deliver shares under both the 2001 and 2011 Plans. Net stock-based compensation expense was $7.0 million and $21.4 million for the respective three and nine months ended September 30, 2017, and $7.3 million and $21.5 million for the respective three and nine months ended October 1, 2016. Cash received from stock purchase and option plan exercises during the three and nine months ended September 30, 2017, totaled $1.6 million and $36.2 million, respectively. Cash received from stock purchase and option plan exercises during the three and nine months ended October 1, 2016, totaled $4.0 million and $32.4 million, respectively. The tax benefit realized from both the exercise and vesting of share-based payment arrangements was $0.8 million and $12.9 million for the respective three and nine months ended September 30, 2017, and $1.8 million and $14.9 million for the respective three and nine months ended October 1, 2016. Stock Options Stock options are granted with an exercise price equal to the market value of a share of Snap-on’s The fair value of each stock option award is estimated on the date of grant using the Black-Scholes valuation model. The company uses historical data regarding stock option exercise and forfeiture behaviors for different participating groups to estimate the period of time that options granted are expected to be outstanding. Expected volatility is based on the historical volatility of the company’s stock for the length of time corresponding to the expected term of the option. The expected dividend yield is based on the company’s historical dividend payments. The risk-free interest rate is based on the U.S. treasury yield curve on the grant date for the expected term of the option. The following weighted-average assumptions were used in calculating the fair value of stock options granted during the nine months ended September 30, 2017, and October 1, 2016, using the Black-Scholes valuation model; there were no stock options granted during the three months ended September 30, 2017, or October 1, 2016: Nine Months Ended September 30, October 1, 2016 Expected term of option (in years) 5.15 5.05 Expected volatility factor 22.01% 22.17% Expected dividend yield 1.63% 1.77% Risk-free interest rate 1.78% 1.04% A summary of stock option activity as of and for the nine months ended September 30, 2017, is presented below: Shares (in thousands) Exercise Remaining (in years) Aggregate (in millions) Outstanding at December 31, 2016 3,011 $ 100.78 Granted 655 168.71 Exercised (278) 87.00 Forfeited or expired (71) 153.52 Outstanding at September 30, 2017 3,317 114.22 6.6 $ 127.7 Exercisable at September 30, 2017 2,108 90.90 5.3 122.5 * Weighted-average The weighted-average grant date fair value of options granted during the nine months ended September 30, 2017, and October 1, 2016, was $31.13 and $22.99, respectively.

As of September 30, 2017, there was $23.3 million of unrecognized compensation cost related to non-vested Performance Awards Performance awards, which are granted as performance share units (“PSUs”) and performance-based RSUs, are earned and expensed using the fair value of the award over a contractual term of three years based on the company’s performance. Vesting of the performance awards is dependent upon performance relative to pre-defined The PSUs have a three-year performance period based on the results of the consolidated financial metrics of the company. The performance-based RSUs have a one-year two-year The fair value of performance awards is calculated using the market value of a share of Snap-on’s Based on the company’s 2016 performance, 45,502 RSUs granted in 2016 were earned; assuming continued employment, these RSUs will vest at the end of fiscal 2018.

Accounting Policies [Abstract]
Principles of consolidation and presentation	Principles of consolidation and presentation The Condensed Consolidated Financial Statements include the accounts of Snap-on “Snap-on” Snap-on’s 10-K Snap-on Snap-on Snap-on’s In the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for the fair presentation of the Condensed Consolidated Financial Statements for the three and nine month periods ended September 30, 2017, and October 1, 2016, have been made. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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.
Financial Instruments	Financial Instruments The fair value of the company’s derivative financial instruments is generally determined using quoted prices in active markets for similar assets and liabilities. The carrying value of the company’s non-derivative
New Accounting Standards	New Accounting Standards The following new accounting pronouncement was adopted in fiscal year 2017: In January 2017, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles – Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment value. Snap-on The following new accounting pronouncements, and related impacts on adoption, are being evaluated by the company: In August 2017, the FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) – Targeted Improvements to Accounting for Hedging Activities No. 2017-12 In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715) – Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost non-service-cost The ASU is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods; early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The amendments in this ASU are to be applied retrospectively. The company does not expect the adoption of this ASU to have a significant impact on its consolidated income statement. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740) – Intra-Entity Transfers of Assets Other Than Inventory In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230) In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326) No. 2016-13 In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) No. 2016-02 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) Entities have the option of adopting this standard using either a full retrospective approach or a modified retrospective approach (i.e., through a cumulative-effect adjustment directly to retained earnings at the time of adoption). Snap-on As of September 30, 2017, and subject to the company’s ongoing evaluation of new transactions and contracts, the company has substantially completed its evaluation of the expected impact of adopting Topic 606 and anticipates that the adoption of this standard will not have a significant impact on the company’s consolidated financial statements. The company believes that the adoption will result in the recognition of an inventory asset related to certain product returns by increasing the returns liability and an inventory asset for the anticipated value of the returns; the corresponding increase in the inventory asset and returns liability is expected to be in the range of $24 million to $28 million at the date of adoption. The adoption will also result in the recognition of an increase in the inventory obsolescence reserve related to the anticipated value on returns in the range of $2 million to $3 million with a corresponding adjustment to beginning retained earnings. The company expects to adopt Topic 606 at the beginning of its 2018 fiscal year using the modified retrospective approach.
