Alexander ★★★★★

These worked perfectly for locking a pulley onto a motor shaft in my shop. The hex socket drive was clean and the black oxide finish seems like it'll resist rust well.

Elizabeth Y. ★★★★★

The knurled body makes these set screws easy to handle even with oily fingers, and the black oxide finish seems tough enough for repeated adjustments in a jig I'm building.

David Y. ★★★★★

The hex socket drive gave me a really secure grip when tightening down on a steel shaft—no slipping at all. These knurled cup points held firmly without damaging the surface, exactly what I needed for a precise clamping job.
