Andrew Q. ★★★★★

I’ve been through a few packs of these little #4-40 screws on my fixture builds, and they’ve never let me down. The hex socket drive grips cleanly with a standard Allen key, and the alloy steel feels sturdy while tapping into aluminum without stripping. Exactly what I look for in precision fasteners

Ella N. ★★★★★

Perfect fit for the tiny jig I was building—these alloy steel screws feel much more solid than the cheap zinc ones I’ve tried before.

Victoria W. ★★★★★

The hex socket drive on these #4-40 screws bites perfectly into my Allen key, making assembly on a small jig much smoother than I expected. For the price, getting a full 200-pack of alloy steel hardware this precise is a steal.
