Kevin ★★★★★

I needed some industrial-grade fasteners for a custom workbench build, and these alloy steel screws were exactly what I was looking for. The hex socket drive made installation a breeze with my Allen key. Charged perfectly fine with no stripping or issues.

Matthew S. ★★★★★

These screws held up beautifully on my jig build—the black oxide finish looks clean and the threads engaged smoothly with zero binding. For 200 pieces at this price, they’re a solid deal for any shop drawer.

James ★★★★★

The hex socket drive on these is machined perfectly, so my Allen key seats deep with zero wobble. I've used about fifty on my latest fixture build and not one stripped or showed a burr. For the price per piece, this box is a steal.
