The hex socket drive bit right into my wrench without any wobble, and the black oxide finish looks clean and uniform across all 50 screws. Used a dozen for a custom jig build and the partial threading gave just the right grip depth.

These all came out of the bag perfectly uniform, threading through the fixture with zero binding. The black oxide finish gives them a clean, professional look for a jig I've been building.

Finally got around to mounting a jig that needed these exact dimensions and the partially threaded section lined up perfectly for clamping. The black oxide finish gives them a nice clean look once installed.
