Customer Reviews (4.8 / 5 · 5 reviews)

Brian F. ★★★★★

The knurled cup point grips tight on my shaft, even with vibration. These set screws hold position perfectly in tight spots where a wrench can't reach.

Joseph ★★★★★

The hex drive let me really torque these down in a tight spot on my mower without stripping. The zinc plating seems solid, and the knurled cup point held firm against the shaft.

Andrew E. ★★★★★

These set screws have a nice sharp bite to them once they're tightened down, and the zinc plating looks clean. The knurled cup point grabbed my shaft securely without slipping. Worked perfectly for locking a collar in place on a small machine build.
