Fastenal ( FAST ) reported first-quarter revenue and profit in-line with Wall Street's estimates on Friday, as higher-value contracts for its fasteners and other industrial supplies helped it offset weaker demand from manufacturing and construction sectors.

The company said more customers - factories, warehouses and construction sites among others - crossed the threshold of $10,000 per month in purchases; its lower-spending customers also showed modest improvement.

The threat of President Donald Trump's tariffs prompted businesses to front-load goods in the first quarter to bypass duties. But it also made them refrain from big investments in sectors such as construction, affecting demand for Fastenal's ( FAST ) products.

The Winona, Minnesota-based company makes fasteners - one of its biggest revenue generators - and other industrial supplies such as protective wear and communication equipment.

Fastenal's ( FAST ) gross profit margin fell to 45.1% of total sales from 45.5% a year earlier, driven by a higher proportion of sales to larger, lower-margin customers and increased transportation costs.

Shares of the company, which holds a market value of $43.5 billion, fell 1% to $75.1 in premarket trading.

It reported net sales of $1.96 billion in the quarter ended March 31, marginally above analysts' estimates of $1.95 billion, according to data complied by LSEG.

The nuts and bolts maker posted a profit of 52 cents per share, in line with Wall Street estimates.

Sales of fasteners fell to 30.3% of the company's total sales, compared with 31.5% a year earlier. Its non-fasteners sales grew to 69.7% of total sales from 68.5% previously.
