Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	(1) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Fastenal Company and subsidiaries (collectively referred to as the company, Fastenal, or by terms such as we, our, or us) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. They do not include all information and footnotes required by U.S. GAAP for complete financial statements. However, except as described herein, there has been no material change in the information disclosed in the Notes to Consolidated Financial Statements included in our consolidated financial statements as of and for the year ended December 31, 2020. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Impact of COVID-19 The COVID-19 pandemic has impacted and could further impact our operations and the operations of our suppliers and vendors as a result of quarantines, facility closures, illnesses, and travel and logistics restrictions. The extent to which the COVID-19 pandemic impacts our business, results of operations, and financial condition will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the duration, spread, severity, and impact of the COVID-19 pandemic, the effects of the COVID-19 pandemic on our customers, suppliers, and vendors and the remedial actions and stimulus measures adopted by federal, state, and local governments, and to what extent normal economic and operating conditions can resume. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of any economic recession or depression that has occurred or may occur in the future. Therefore, the Company cannot reasonably estimate the future impact at this time. Recently Issued Accounting Pronouncements In March 2020, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , which provides temporary optional expedients and exceptions to U.S. GAAP on contract modifications, hedging relationships, and other transactions affected by reference rate reform to ease entities' financial reporting burdens as the market transitions from the London Interbank Offered Rate (LIBOR) and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made, hedging relationships entered into, and other transactions affected by reference rate reform, evaluated on or before December 31, 2022, beginning during the reporting period in which the guidance has been elected. We are currently evaluating the impact of the new guidance on our condensed consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue	(2) Revenue Revenue Recognition Net sales include products and shipping and handling charges, net of estimates for product returns and any related sales incentives. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring products. All revenue is recognized when we satisfy our performance obligations under the contract. We recognize revenue by transferring the promised products to the customer, with the majority of revenue recognized at the point in time the customer obtains control of the products. We recognize revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. We estimate product returns based on historical return rates. Using probability assessments, we estimate sales incentives expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Revenues are attributable to countries based on the selling location from which the sale occurred. Disaggregation of Revenue Our revenues related to the following geographic areas were as follows for the periods ended March 31: Three-month Period 2021 2020 United States $ 1,187.8 1,166.7 Canada and Mexico 176.8 158.4 North America 1,364.6 1,325.1 All other foreign countries 52.4 41.9 Total revenues $ 1,417.0 1,367.0 The percentages of our sales by end market were as follows for the periods ended March 31: Three-month Period 2021 2020 Manufacturing 68.0 % 67.9 % Non-residential construction 10.8 % 12.3 % Other 21.2 % 19.8 % 100.0 % 100.0 % The percentages of our sales by product line were as follows for the periods ended March 31: Three-month Period Type Introduced 2021 2020 Fasteners (1) 1967 32.5 % 32.9 % Tools 1993 8.6 % 9.4 % Cutting tools 1996 5.0 % 5.4 % Hydraulics & pneumatics 1996 6.3 % 6.6 % Material handling 1996 5.5 % 5.7 % Janitorial supplies 1996 8.5 % 8.3 % Electrical supplies 1997 4.3 % 4.6 % Welding supplies 1997 3.8 % 4.1 % Safety supplies 1999 21.5 % 19.8 % Other 4.0 % 3.2 % 100.0 % 100.0 % (1) The fasteners product line represents fasteners and miscellaneous supplies.

Stockholders' Equity Note [Abstract]
Stockholders' Equity	(3) Stockholders' Equity Dividends On April 12, 2021, our board of directors declared a quarterly dividend of $0.28 per sha re of common stock to be paid in cash on May 25, 2021 to shareholders of record at the close of business on April 26, 2021. Since 2011, we have paid quarterly cash dividends, and in 2020, we paid a special cash dividend late in the year. Our board of directors currently intends to continue paying quarterly cash dividends, provided that any future determination as to payment of dividends will depend on the financial condition and results of operations of the company and such other factors as are deemed relevant by the board of directors. The following table presents the cash dividends either paid previously or declared by our board of directors for future payment on a per share basis: 2021 2020 First quarter $ 0.28 $ 0.25 Second quarter $ 0.28 $ 0.25 Third quarter $ 0.25 Fourth quarter $ 0.25 Fourth quarter (special) $ 0.40 Total $ 0.56 $ 1.40 Stock Options The following tables summarize the details of options granted under our stock option plans that were outstanding as of March 31, 2021, and the assumptions used to value these grants. All such grants were effective at the close of business on the date of grant.

Generally, each option will terminate approximately ten years after the grant date. The fair value of each share-based option is estimated on the date of grant using a Black-Scholes valuation method that uses the assumptions listed above. The risk-free interest rate is based on the U.S. Treasury rate over the expected life of the option at the time of grant. The expected life is the average length of time over which we expect the employee groups will exercise their options, which is based on historical experience with similar grants. The dividend yield is estimated over the expected life of the option based on our current dividend payout, historical dividends paid, and expected future cash dividends. Expected stock volatilities are based on the movement of our stock price over the most recent historical period equivalent to the expected life of the option. Compensation expense equal to the grant date fair value is recognized for all of these awards over the vesting period. The stock-based compensation expense for the three-month periods ended March 31, 2021 and 2020 was $1.5 and $1.6, respectively. Unrecognized stock-based compensation expense related to outstanding unvested stock options as of March 31, 2021 was $16.6 and is expected to be recognized over a weighted average period of 4.41 years . Any future changes in estimated forfeitures will impact this amount. Earnings Per Share The following tables present a reconciliation of the denominators used in the computation of basic and diluted earnings per share and a summary of the options to purchase shares of common stock which were excluded from the diluted earnings per share calculation because they were anti-dilutive: Three-month Period Reconciliation 2021 2020 Basic weighted average shares outstanding 574,336,112 573,904,156 Weighted shares assumed upon exercise of stock options 2,210,857 1,414,674 Diluted weighted average shares outstanding 576,546,969 575,318,830 Three-month Period Summary of Anti-dilutive Options Excluded 2021 2020 Options to purchase shares of common stock 711,977 891,290 Weighted average exercise prices of options $ 48.00 38.00

Income Tax Disclosure [Abstract]
Income Taxes	(4) Income Taxes We file income tax returns in the United States federal jurisdiction, all states, and various local and foreign jurisdictions. We are no longer subject to income tax examinations by taxing authorities for taxable years before 2017 in the case of United States federal examinations, and with limited exceptions, before 2015 in the case of foreign, state, and local examinations. During the first quarter of 2021 , there were no material changes in unrecognized tax benefits. During 2020, we deferred approximately $30.0 in payroll taxes as allowed under the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) which was signed into law in March 2020 to help businesses navigate COVID-19 related challenges. The deferred payroll taxes will be paid during the third quarter of 2021.

Leases [Abstract]
Operating Leases	(5) Operating Leases Certain operating leases for pick-up trucks contain residual value guarantee provisions which would generally become due at the expiration of the operating lease agreement if the fair value of the leased vehicles is less than the guaranteed residual value. The aggregate residual value guarantee related to these leases is approximately $88.1 . We believe the likelihood of funding the guarantee obligation under any provision of the operating lease agreements is remote.

The Credit Facility includes a committed letter of credit subfacility of $55.0. Any borrowings outstanding under the Credit Facility for which we have the ability and intent to pay using cash within the next twelve months, will be classified as a current liability. The Credit Facility contains certain financial and other covenants, and our right to borrow under the Credit Facility is conditioned upon, among other things, our compliance with these covenants. We are currently in compliance with these covenants. Borrowings under the Credit Facility generally bear interest at a rate per annum equal to the London Interbank Offered Rate (LIBOR) for interest periods of various lengths selected by us, plus 0.95%. We pay a commitment fee for the unused portion of the Credit Facility. This fee is either 0.10% or 0.125% per annum based on our usage of the Credit Facility.

We recognize revenue for shipping and handling charges at the time the products are delivered to or picked up by the customer. We estimate product returns based on historical return rates. Using probability assessments, we estimate sales incentives expected to be paid over the term of the contract. The majority of our contracts have a single performance obligation and are short term in nature. Sales taxes and value added taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Revenues are attributable to countries based on the selling location from which the sale occurred.
