Jason A. ★★★★★

The alloy steel feels really solid, and the full dog point seated perfectly against the mating surface for a secure hold. I went through about 50 of them already for a jig build and haven't had a single one strip.

Andrew ★★★★★

The hex socket drive made it easy to tighten these into tight spots on my jig. I was impressed that all 250 screws had clean, consistent threads without any burrs.

Andrew S. ★★★★★

I needed a bunch of M4 set screws for a jig I’m building, and these came through exactly as described. The hex drive made tightening them in a cramped spot a breeze without rounding off. Already ordered another pack for the next project.
