Installed these as the axle on a set of heavy-duty steel rollers, and the precision ground shoulder spins true with zero wobble. The black oxide finish hasn't chipped or worn despite constant use. Exactly what I needed for a reliable bearing surface.

Used these as pivot pins on a custom jig, and the hex socket made installation a breeze. The black oxide finish looks great and seems durable.

The precision ground shoulder on these screws fit perfectly into my jig’s bearing surfaces, and the thermal black oxide finish resists wear better than I expected. Installation was straightforward with a hex key, and they’ve held up through repeated adjustments without any play.
