Michael H. ★★★★★

The flat heads sit flush against my fixture plates without any wobble, and the hex socket grips the driver firmly every time. I've used about 40 of these on a jig build so far, and not a single one has stripped or felt soft. For the price per hundred, these are a solid deal.

Ruby Q. ★★★★★

The hex drive on these fit perfectly, making them easy to install in tight spots for a jig I was building. They tightened down flush without stripping, and the 18/8 stainless feels solid compared to cheaper hardware I've used.

Avery X. ★★★★★

I was a little nervous the flat heads would strip, but these 18/8 stainless screws held up perfectly under my jig’s torque. They’re a snug fit in the hex socket, and the 100-pack gives me plenty for future tooling projects.
