The hardened hex drive took a lot of torque without stripping, which I was worried about with such a long shoulder. I used these as pivot points on a custom press fixture and the fit was dead on with no wobble. They look and feel like serious hardware, exactly what I needed for a repeat-use jig.

These bolts slid perfectly into the jig I’m building; the hex drive made tightening them a breeze even in a tight spot. The black oxide finish looks professional and seems tough against scratches.

The precision ground shoulder is dead-on for the pivot I needed on a custom jig—no wobble at all. These are solid pieces of alloy steel, and the black oxide finish makes cleanup a breeze.
