Ruby ★★★★★

Installed about two dozen of these today holding down some heavy jig fixturing, and the hex socket drive made easy work of tightening them down without cam-out. The black oxide finish feels like it'll hold up well to shop grime.

Edward ★★★★★

These black oxide screws fit perfectly into my jig fixtures and the hex drive made installation a breeze with no stripping. The 50-pack is great value for the shop.

Scarlett G. ★★★★★

I needed a handful to replace worn screws on a jig, and the socket drive made installation with a hex wrench quick and easy. The black oxide finish adds a nice, clean look to the assembly.
