Leo M. ★★★★★

The black oxide finish really holds up well on these cup point screws—no rust after a few months in a damp shop. They bottom out cleanly in tapped holes, which saved me time on a recent shaft assembly.

Natalie B. ★★★★★

I needed a few of these to lock a pulley onto a motor shaft, and the cup point bit into the shaft firmly without stripping. The black oxide finish feels durable and should resist rust well in my shop.

Grace ★★★★★

The hex socket drive made installation straightforward with a standard Allen key, and the black oxide finish looks uniform across all 100 pieces. I used these for securing a pulley assembly, and the cup point held firm without stripping.
