These came in with a flawless hex socket and that black oxide finish looks properly done, not just cosmetic. The precision ground shoulder let me set up a clean axle on a small cart without any annoying wobble.

The precision ground shoulder on these screws is noticeably smoother than cheaper alternatives, making them ideal for a tight pivot fit. They seated perfectly with no wobble, and the black oxide finish looks clean on the assembly.

The hex socket drive fits perfectly with my 5/8" driver, and the thermal black oxide gives them a nice, uniform finish that resists scuffing during assembly. I used these as pivot points on a jig, and the precision ground shoulder ran true with no wobble whatsoever.
