Benjamin T. ★★★★★

The knurled cup point bit into the shaft perfectly for securing a pulley, and the zinc plating makes them look clean even after a few turns. Used a dozen so far without any stripping issues, which is a win in my book.

Aurora ★★★★★

Perfect for locking down a stubborn adjustment collar I was working on, the 100-count package gives you plenty of spares for future jobs. The knurled cup point really bites into the shaft and stays put under vibration, and the hex socket drive lets you get full torque even with a tight clearance.

Lucy S. ★★★★★

Knurled cup point gripped the shaft much better than the smooth set screws I've used before, and the hex socket made tightening in a cramped spot a breeze. The zinc plating looks clean and these 100 pieces should last me through several projects.
