Used these for a precision fixture build and the hex drive seated perfectly without any stripping. The black oxide finish gives them a nice, uniform look and seems to resist minor scuffs during assembly.

I swapped out the standard bolts on my jig table with these and the black oxide finish makes them look almost too good for the shop. The hex socket drive seated perfectly with my Allen key, no stripping or wobble during install.

Used these to rebuild a custom tooling fixture, and the black oxide coating gave them a nice consistent finish that held up under torque. The hex socket drive seated perfectly with my driver, no stripping or cam-out issues. Exactly what I needed for precision assemblies.
