Customer Reviews (4.4 / 5 · 5 reviews)

David O. ★★★★★

The knurled cup point really digs in nicely on my aluminum fixture, no slipping at all. I used these on a custom jig and the hex socket drive made installation in the tight spot a breeze.

Nicholas C. ★★★★★

I needed a small screw to fit a tight spot on a jig, and the knurled cup point tip grabbed securely without slipping. The hex socket drive let me apply plenty of torque even in that cramped corner.

Avery ★★★★★

The knurled cup point grips the shaft firmly without marring it, which was exactly what I needed for a stubborn pulley. The hex socket drive made torquing them down in a cramped spot a breeze, and all 100 arrived clean with no stripped threads.
