Michael ★★★★★

The black oxide finish on these set screws holds up well against corrosion, and the knurled cup point locks tight on a shaft without slipping. They drove in cleanly with a hex key, exactly what I needed.

Benjamin ★★★★★

I needed a headless screw that wouldn’t back out during assembly, and the hex socket drive made tightening in tight spaces a breeze. The thermal black oxide finish seems tough, and the 100-pack means I have spares for future projects.

Julian L. ★★★★★

The knurled cup point really bites into the shaft, which gave me a solid hold on a stubborn pulley I was repairing. I also appreciate that the black oxide coating seems to resist rust better than the plain steel ones I’ve used before.
