Robert M. ★★★★★

The hex socket drive made it easy to get these tiny screws snug without stripping, and the black oxide coating seems durable. Perfect for keeping a small gear collar in place on my mill.

Robert E. ★★★★★

These little set screws cinch down firmly without stripping, and the black oxide finish gives them a nice corrosion-resistant look. I used them to lock a pulley onto a motor shaft, and they held perfectly after a full day of running.

Ava ★★★★★

Finally found the right size for a small gear I was fixing, and these #4-40 set screws threaded in perfectly without any stripping. The black oxide finish looks clean and seems like it’ll hold up well against light corrosion.
