Used these as axle pins on a custom jig; the ground shoulder gave a smooth, tight fit with no wobble. The black oxide finish held up well against light oil and debris during testing.

Installing these on a conveyor pivot point, the hex socket drive made torquing them down a breeze compared to slotted alternatives. The shoulder fit snugly into the bearing housing with zero play. Exactly what I needed for a precise mechanical joint.

The precision ground shoulder on these screws is flawless—they spin true and smooth in my pivot assembly. The thermal black oxide finish looks great and seems durable, and the hex drive made installation a breeze.
