Customer Reviews (4.8 / 5 · 5 reviews)

Benjamin O. ★★★★★

The black oxide finish on these screws really holds up well in my shop jigs—no rust after a month of use. Pack of 1500 is more than I’ll need for a while, but the price per screw is hard to beat for USA-made alloy steel.

Adam ★★★★★

These screws are perfect for my latest jig build—the hex socket drive seated firmly without any stripping. The black oxide finish seems durable and consistent across all 1500 pieces, which is exactly what I needed for high-torque applications.

Joseph R. ★★★★★

I was a bit worried about buying such a large quantity, but these socket cap screws are consistently well-formed and the black oxide finish feels durable. Threaded them into a few jigs without any binding, which saved me time on assembly.
