--- title: "Fastenal: Competitors" description: "Fastenal compared with companies that share its SEC industry classification: revenue, growth and margins from SEC filings, and how the peer group is chosen." canonical: https://www.getswoopr.com/stocks/companies/fastenal/competitors/ source: "Swoopr Investment: https://www.getswoopr.com" --- # Fastenal: Competitors & Industry Structure ## Direct Answer SEC EDGAR classifies Fastenal under SIC code 5200 (Retail-Building Materials, Hardware, Garden Supply). Among Swoopr's S&P 500 Equal Weight companies, 4 others share that classification; by latest reported revenue, Fastenal ranks 3 of 5. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes. ## How Does Fastenal Compare With Its Peers? | Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin | | --- | --- | --- | --- | --- | | [Sherwin-Williams (SHW)](https://www.getswoopr.com/stocks/companies/sherwin-williams/) | $23.6 billion FY2025 | 2.1% | n/a | 10.9% | | [Tractor Supply (TSCO)](https://www.getswoopr.com/stocks/companies/tractor-supply/) | $15.5 billion FY2025 | 4.3% | 9.5% | 7.1% | | **Fastenal (FAST)** | $8.2 billion FY2025 | 8.7% | 20.2% | 15.3% | | [GrowGeneration Corp.

Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars. | Measure | Fastenal | Median of filers | Rank | | --- | --- | --- | --- | | Revenue | $8.2 billion | $8.2 billion | 3 of 5 | | Revenue growth | 8.7% | 2.1% | 1 of 5 | | Net margin | 15.3% | 7.1% | 1 of 5 | A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality. ## Where These Numbers Come From Every figure on this page is a value Fastenal reported in its own SEC filings, read from the SEC's XBRL data (accession 0000815556-26-000009 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary. Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation. ## Frequently Asked Questions ### Who are Fastenal's competitors?
