Customer Reviews (4.2 / 5 · 5 reviews)

Olivia S. ★★★★★

Fit perfectly into a tight spot on a jig fixture I was building, and the cup point bit into the shaft cleanly without any slipping. The black oxide finish looks nicely uniform across all 100 pieces, which matters for corrosion resistance in my shop.

Sophia ★★★★★

Used these to secure a motor pulley to a keyed shaft and the cup point bit in perfectly without slipping during tightening. The black oxide finish feels sturdy and hasn't shown any rust yet despite being in a damp garage. Pack of 100 should last me through multiple projects.

Brian ★★★★★

The black oxide finish on these cup point screws looks great and should resist rust well in my tooling jigs. The hex socket drive made threading them into tight spots a breeze. Waited a while for a full pack of these, and they were worth it.
