Customer Reviews (4.4 / 5 · 5 reviews)

Joseph D. ★★★★★

The hex socket drive is a lifesaver when you're torquing these down in a cramped spot—the cup point bites in firmly and holds even under vibration. All 100 arrived clean with no burrs on the threads, which made installation quick.

Sophia ★★★★★

I needed some high-torque set screws for a machinery adjustment, and these M12 cup points bite into the shaft well without slipping. The hex socket drive made tightening in that cramped spot much easier than I expected. Solid buy for the price.

Charlotte ★★★★★

These set screws have a nice, aggressive cup point that really bites into the shaft, perfect for keeping a gear hub locked in place. The hex socket drive lets me get them tight with a standard Allen key, even in a cramped area.
