Had to swap out a worn set screw on a motor shaft and these fit perfectly—the hex socket drive made installation a breeze with my Allen wrench. They're steel so they should hold up well against vibration. Exactly what I needed for the job.

Replaced the cheap set screws on a mower shaft with these and the hex socket made installation much easier than fighting a slotted head. The steel feels solid and I'm confident they'll hold up.

Installed these to lock down a pulley on a motor shaft, and the steel threads bit in nicely without stripping. They held firm on an assembly that sees moderate vibration. Exactly what I needed for that application.
