The hex key fit perfectly into the socket, and these set screws tightened up a stubborn vibrating joint on my press without stripping. The knurled cup point really dug in securely.

I needed these for a heavy machinery alignment and the knurled cup point really digs in securely without slipping. The hex socket drive made installation effortless even with limited access. Solid set screws for the price.
