Exactly what I needed for a jig I’m building at work—the hex socket drive fits my Allen key perfectly, and the partial threading gives great grip in the clamping area. Solid feel in the hand, and the black oxide looks clean once installed.

The black oxide finish on these is flawless, and the hex socket drive grips the allen key without any slip. Threads cut cleanly into my steel fixture plate, and all 100 pieces arrived with zero burs. Just what I needed for a precision assembly job.

Installing these on a jig today and the hex socket drive grabbed my Allen key perfectly — no stripping at all. The black oxide finish looks professional and seems like it'll resist rust well.
