Customer Reviews (3.8 / 5 · 5 reviews)

Hazel V. ★★★★★

These set screws held a gear hub perfectly on my mill after I torqued them down with a hex key. The 3 1/2 inch length gave me plenty of thread engagement, and the alloy steel felt super solid the whole time. Just the right amount of grip from the cup point for a permanent lock.

Sophia T. ★★★★☆

The cup point bites into the shaft nicely and holds firm under vibration, which is exactly what I needed for a stubborn pulley. Only gripe is the packaging—a few arrived with a bit of oil residue, but they cleaned up fine. Solid buy for the price.

Ellie ★★★★☆

The cup point really bites into the shaft, which I needed for a stubborn gear repair. At 3-1/2 inches long, they were just right for my application, though one screw had a slightly rough thread.
