Natalie S. ★★★★★

The precision ground shoulder is exactly what I needed for a jig's pivot point—no slop at all. The hex socket drive made installation quick, even in a tight spot.

Carter C. ★★★★★

I needed a precise axle for a small assembly, and the ground shoulder on these screws fit perfectly without any wobble. The black oxide finish also gives them a nice, professional look.

Violet ★★★★★

The precision-ground shoulder is exactly what I needed for a clean pivot point on a jig I’m building—no wobble at all. The black oxide finish looks sharp and the hex drive seated snugly on my Allen key. Twenty-five in the pack means I’ve got spares for the next project.
