These are exactly what I needed for a custom pivot assembly; the hex drive made torquing them down a breeze and that thermal black oxide finish looks sharp. The shoulder fit snugly into my bearing without any play, solid quality for the price.

The precision ground shoulder made it easy to align as a pivot point in my jig, and the black oxide finish slides smooth without any binding.

The hex socket drive bites down clean without any wobble, and the thermal black oxide finish has held up nicely after mounting a couple of these as pivot points. Used them as axles on a small jig and they spin true with zero play. Exactly what I needed for tight clearance work.
