Cap Screw, M8x20, Socket Head

Whoever packed these got the threading right—fully threaded from end to end—so my M8 nut spun on cleanly without any binding. 20mm length was exactly what the old part was, and the 6mm hex drive sat snug in my driver. No complaints here.

The 6mm hex drive fit my allen wrench perfectly, and the fully threaded shaft grabbed nicely in the aluminum bracket I was mounting. No wobble at all once torqued down, just a solid hold for a machine guard that kept shifting before.

The fully threaded M8x20 made torquing it down in a tight spot a breeze, and the socket head sat flush without any wobble. I've got a box of these now for future repairs, and the 6mm hex drive is exactly what my wrench needed.
