Ruby J. ★★★★★

The black oxide finish on these M6-1 x 18mm screws looks durable and hasn’t chipped during assembly work. They’re a solid upgrade for my jigs and fixtures, with the hex socket driving smoothly and holding tight.

Benjamin K. ★★★★★

I’ve been using these on a custom tooling fixture, and the flat head sits perfectly flush every time. The hex drive engages without slipping, which is a nice change from cheaper screws I’ve tried.

Alexander ★★★★★

Used these for a jig I was building and the flat heads sit perfectly flush every time. The hex socket drive gives a nice clean grip without stripping.
