Benjamin ★★★★★

Had to swap out some worn fasteners on a machinery shaft and these black oxide screws fit perfectly with no wobble. The hex socket drive made installation quick and the knurling held tight. Exactly the clamp-up I needed for those tight tapped holes.

Zoe ★★★★★

The knurled cup point gives these set screws a surprisingly solid bite, and the black oxide finish feels durable right out of the package. I used them to lock a pulley onto a motor shaft and they haven’t budged under load.

Claire ★★★★★

I needed a set screw that wouldn't back out on a high-vibration motor shaft, and these knurled points definitely hold their bite. The black oxide finish seems durable and resists rust so far.
