Fastenal Company FAST

The business

Fastenal is the largest industrial-distribution platform in North America, selling the boring stuff that keeps factories and construction sites running: threaded fasteners (the original product, now about 30% of mix), plus cutting tools, safety equipment, janitorial supplies, electrical, hydraulics, and MRO consumables. The customer base is roughly 70% manufacturing (heavy and light), 10% non-residential construction, and the rest split across government, transportation, mining, and agriculture. The engine is the Onsite + FMI program: ≈2,200 staffed in-customer locations where Fastenal personnel sit inside the customer's plant, plus ≈130,000+ FMI vending and bin-stock devices that auto-replenish. Onsite + FMI customers now drive ≈65% of revenue and are growing low double digits while the legacy branch channel shrinks; this is the slice doing the work, growing 3-4x the rate of the rest of the book at structurally higher gross margins because the switching cost (ripping out vending infrastructure embedded in a customer's production line) is real.

What the financials don't show is the cyclical position. The PMI has been hovering at or below 50 for most of 2024-2025; Fastenal's daily sales growth ran +3% to +5% organic through most of FY25 with December 2025 accelerating to +7%, which the company attributes to easier comps plus early signs of manufacturing restock. Heavy manufacturing (≈42% of sales) is the swing factor. Daily sales per business day is the leading indicator to watch, and management calls out signed Onsite contracts as the forward-bookings proxy: FY25 signed ≈400 net new Onsites against a stated 375-400 target, with the FY26 target raised to 425-450. That signing pace is the asymmetry's tell.
