Customer Reviews (4.8 / 5 · 5 reviews)

George ★★★★★

The cup point on these M8 screws really bites into the shaft, no slipping at all during assembly. They’re perfect for locking a pulley in place on a tight build, and the hex socket drive makes adjustments easy even in cramped spots. Good value for a hundred pieces.

Kevin ★★★★★

These set screws are exactly the right hardness for the job—the cup point bites in cleanly and doesn’t strip out even after I torqued them down hard with a hex key. The 100-pack feels like solid value for the price, and the 40mm length was perfect for my application.

George P. ★★★★★

The hex socket drive was a lifesaver when I needed to cinch them down in a spot where a wrench couldn't reach. The cup point grips the shaft firmly, and the alloy steel feels solid enough for repeated adjustments.
