These set screws bit into the shaft perfectly thanks to that sharp cup point, and the black oxide finish looks clean and doesn't rust easily. Exactly what I needed for a tight hold in a tapped hole.

The cup point bites into the shaft exactly where I set it, and the black oxide finish makes them look clean even after a few installations. Took a bit of effort to drive them in, but once seated, they held firm without any wobble.

I was worried about stripping the hex socket, but these drove in cleanly with no cam-out. The black oxide finish looks consistent and should hold up well in a tapped hole.
