Customer Reviews (4.8 / 5 · 5 reviews)

Avery L. ★★★★★

The black oxide finish on these screws looks really clean and professional, and the knurled cup point held my shaft collar in place without slipping. Perfect size for tight adjustments on a small assembly jig I was building.

John ★★★★★

The hex socket drive on these set screws made installation easy even in a tight spot, and the black oxide finish looks clean against the shaft. They hold firm without slipping under vibration. Exactly what I needed for a quick repair project.

Ava ★★★★★

These knurled cup points really bite into the shaft, no slipping at all once tightened down. The hex socket drive made installation quick in a tight spot.
