Swapping out a stripped jig bolt on my drill press, these socket cap screws fit perfectly and the hex drive seated without any wobble. The partially threaded shaft was exactly what I needed for this fixture.

The black oxide finish took a beating during install and still looks flawless, and the hex socket drive grabbed perfectly with no stripping. These are holding up great on my jig setup, worth the few bucks extra for the alloy steel.

The partial threading on these screws made them perfect for a jig I was building where I needed extra grip near the head. They snugged in tight without any stripping on the hex drive.
