Abigail ★★★★★

Used a few of these to lock down a pulley on a 3D printer build, and the 18-8 stainless holds up perfectly without rusting. The flat point grips the shaft nicely without marring it. Great value for getting 90 pieces of this tiny hardware.

Adam A. ★★★★★

Grabbed a pack to secure a small gear on a shaft, and the 18-8 stainless steel feels solid—no rust issues so far. The flat point seats nicely without chewing up the shaft surface.

Elizabeth F. ★★★★★

The hex socket drives cleanly with my Allen key, and the 18-8 stainless has that solid, weighty feel you want for a set screw. I’ve got a few collars on a small shaft that’ve held tight through a week of vibration, no backing out yet.
