Customer Reviews (4.8 / 5 · 5 reviews)

Madison O. ★★★★★

These are beefier than expected, which is good since they're 1 3/4" long. The knurled cup point really digs in and holds tight, and the hex socket drove smoothly on a heavy bracket install.

Olivia K. ★★★★★

The hex socket drive made it easy to tighten these set screws in a cramped machine area. The alloy steel feels solid and durable, perfect for high-torque adjustments.

Thomas ★★★★★

Threaded these into a motor mount that kept shaking loose, and the knurled cup point locked in tight after just a few turns with a hex key. At 1-3/4 inches long, they gave me enough grip to reach through the bracket, and the alloy steel feels solid even under high torque.
