Customer Reviews (5.0 / 5 · 5 reviews)

Henry ★★★★★

Installed these in a gearbox shaft and the knurled cup point held tight under vibration. The black oxide finish hasn't shown any wear after a few weeks of use.

Joshua X. ★★★★★

I needed these for a repair on a milling machine, and the black oxide finish looks like it will resist rust well. The hex drive was cleanly machined and fit my Allen key perfectly without any wobble.

Ruby V. ★★★★★

The knurled cup point grabs the shaft really well once tightened, no slipping at all on my test setup. Took only a few minutes to install them all with a hex key, and the black oxide finish looks clean and professional.
