These shoulder screws have that precise ground surface I needed for a smooth bearing fit on a small axle assembly. The thermal black oxide finish seems durable and the hex socket drive made installation straightforward.

I needed a pivot for a custom jig and the precision ground shoulder on these screws was exactly what I was looking for, they spin smoothly with zero wobble. The thermal black oxide finish also gives them a nice, durable look.

Finally got these to replace a worn pivot pin on a jig, and the precision ground shoulder fits perfectly without any play. The hex socket drive made installation straightforward, and the black oxide finish should help with rust resistance. Exactly what I needed for a solid axle application.
