The hex socket drive made tightening these down in tight spots on my fixture much easier than using a hex key on a standard bolt. They seated flush and the black oxide finish looks clean.

Installed these in a jig for a production run and the hex socket drive handled my torque wrench without any stripping. The M16-2 threads seated perfectly in the pre-tapped holes—solid fit.

The black oxide finish on these screws handled a greasy assembly line without any rust spots, and the hex socket drive made installation a breeze. I’ve used them for a small press rebuild, and they fit perfectly without any stripping.
