Used one as a pivot pin for a jig I built, and the precision ground shoulder fit perfectly with zero play. The thermal black oxide finish also seems like it'll hold up well in my shop.

Finally got around to using these as axles for a small indexing fixture, and the ground shoulder runs dead true in the bushing. The black oxide finish wiped clean and hasn't shown any rust after a few days in the shop.

Had to swap out a worn pivot on my milling jig, these dropped right in. The hex socket drive seats cleanly and the black oxide finish feels tough. Exactly what I needed for a repair that had me stuck.
