The knurled cup point really bites into the shaft without stripping, which is exactly what I need for a secure hold. These set screws are solid alloy steel and the hex drive lets me torque them down nicely in cramped spots.

The knurled cup point bites into the shaft without stripping, even after I torqued it down hard with a hex key in a cramped spot. All the threads came clean out of the bag, no chips or burrs. Solid little fasteners for the price.

Exactly the right size for adjusting my vise jaws in those tight spots where a regular socket won't fit, and the hex drive gives you a solid grip without stripping. The knurled cup point locks in place nicely.
