Harper Z. ★★★★★

I've been using these set screws to secure a pulley on a small motor shaft, and the cup point bites in perfectly without slipping. The thermal black oxide finish also seems to resist rust well in my shop's humid conditions.

Andrew ★★★★★

I needed a few for a small gear shaft repair, and these set screws fit perfectly with the hex drive making installation easy. The thermal black oxide finish looks tough and should resist rust better than plain steel ones I've used.

Jacob V. ★★★★★

The cup point really digs in well and holds tight on a shaft, even after a bit of vibration. Pack of 100 was plenty for my project, and the black oxide finish looks clean and resists rust nicely.
