Installed these as axle pins for a small custom roller fixture and the precision ground shoulder made alignment perfect. The black oxide finish is holding up well so far with no rust.

Used a few of these as pivot pins in a jig I built—the hex drive made installation simple with just an Allen key. The black oxide finish seems tough enough to resist shop grime. Worked perfectly for the application.

The precision ground shoulder on these screws makes them perfect as a pivot point for a jig I’m building—much smoother than using regular bolts. They seated nicely with a hex key, and the black oxide finish hasn’t chipped during installation. Exactly what I needed for this project.
