Jacob D. ★★★★★

Used these to secure a collar on a small motor shaft and the hex socket fit perfectly with no wobble. The black oxide finish feels durable and the threads cut cleanly into the tapped hole.

David L. ★★★★★

The cup point on these set screws grips really well—no slipping once you torque them down. They threaded smoothly into my steel fixture without any binding, which was a relief. Exactly what I needed for a tight assembly job.

Ava ★★★★★

Perfect fit for a delicate indexing fixture I’m building—the cup point grips the shaft solidly without any slippage. Black oxide finish also gave just enough corrosion resistance for the workshop environment.
