Natalie E. ★★★★★

Installed these as pivot pins for a jig and the precision ground shoulder was exactly on spec, so everything spins true without wobble. The black oxide finish has held up well through a few assembly cycles too.

Miles ★★★★★

I was worried the hex drive might strip during installation, but the alloy steel handled the torque beautifully. These shoulder screws are perfect as bearing surfaces for a custom jig I'm building, and the black oxide finish resists oil splatters well.

Julian ★★★★★

The precision ground shoulder is spot-on—measured every one of the 25 and they’re all consistent to within a hair. Using them as axle pins for a small jig I built, and the hex drive seats perfectly without any wobble.
