Fastenal’s strong sales growth continued throughout 2025’s fourth quarter, leading the fasteners, construction and contractor supplies distributor to hit a new annual high-water mark.

The company’s Jan. 20 financial reporting showed that it had $8.2 trillion in 2025 sales — up 8.7% from 2024, with daily sales up 9.1%. Gross margin of 45.0% dipped 10 basis points; operating profit of $1.66 billion on 20.2% margin topped the $1.51 billion/20.0% of a year earlier; and net profit of $1.26 billion increased 9.4%.

For 4Q25, sales of $2.03 billion increased 11.1% year-over-year, with daily sales up by that same amount; gross margin of 44.3% fell 50 bps; operating profit of $384 million on 19.0% margin topped the $345 million/18.9% of a year earlier; and net profit of $294 million increased 12.2%.

December sales of $629 million jumped 16.2% year-over-year, with daily sales up 10.7%. It was the company’s sixth straight month of double-digit daily sales growth, following November’s 11.8%.

Fastenal attributed the 4Q sales growth to a combination of increased sales effectiveness and pricing, with the latter having a 310-340 bps impact year-over-year — up from 240-270 in 3Q.

Meanwhile, the company said market conditions remain sluggish.
