The precision-ground shoulder on these is spot on—measured every one with a mic and they're all dead consistent at 0.5000". Used a few as pivot pins in a fixture and the hex socket drive made install torque easy to control.

Installing these in a jig I built, the hex socket drive made torquing them down much easier than a standard slotted set screw. The black oxide finish seems durable and should resist rust in my shop environment.

The precision ground shoulder made these perfect for a small pivot point I was building, and the black oxide finish looks great and resists wear nicely. Definitely a solid choice for any mechanical project needing a reliable axle or bearing surface.
