Customer Reviews (4.6 / 5 · 5 reviews)

Violet R. ★★★★★

The knurled cup point digs into the shaft with zero slippage, even on a motor I've had vibration issues with. The black oxide finish also looks clean and didn't chip during tightening.

Ava W. ★★★★★

Packed these perfectly into a 1/4" deep tapped hole on a small indexing fixture, and the hex socket drive made installation effortless with a standard Allen key. The all-metal construction feels solid, and the black oxide finish blends in nicely without any glare.

Joseph Y. ★★★★★

The knurled cup point grips the shaft way better than the plain ones I’ve used before, and they threaded in cleanly without any wobble. Got the full hundred-pack for a fraction of what I’d pay elsewhere, so this should last me through several projects.
