Customer Reviews (4.6 / 5 · 5 reviews)

Leo A. ★★★★★

Exactly what I needed for a stubborn pulley repair; the knurled cups really bite into the shaft so nothing slips. The black oxide finish makes them easy to see against the steel I'm working with, too.

Christopher Q. ★★★★★

Finally found set screws that actually hold tight on a shaft without backing out. The black oxide finish on these feels solid, and the knurled cup point bites in nicely.

Sofia ★★★★★

Installed these into a couple of tapped holes on a jig, and the hex socket fit snugly. The thermal black oxide finish has held up well so far, no chipping.
