Customer Reviews (4.8 / 5 · 5 reviews)

Natalie ★★★★★

The hex socket drive made installation incredibly smooth, and the black oxide finish looks clean against the machine's surface. I used these for securing a gear on a custom shaft assembly. They hold tight with no slippage.

Victoria ★★★★★

Installed these to secure a pulley on a motor shaft, and the cup point bites in perfectly without stripping. The hex socket drive makes it easy to get them tight with an Allen key, even in a cramped spot.

Timothy ★★★★★

The black oxide finish on these set screws looks durable and resists rust nicely on my machine tools. They cinch down tight with a hex key and hold firmly without stripping.
