Sofia F. ★★★★★

Had to swap out a stripped set screw on a motor shaft and these threaded in clean without any fuss. The knurled cup point digs in solid, and the black oxide finish makes them look right at home on the machine. Pack of 100 means I won’t be scrambling next time one gets chewed up.

Henry ★★★★★

The knurled cup point grips the shaft way better than the smooth ones I've used, and the thermal black oxide finish looks clean in a tapped hole. These 5/16-24 x 3/8" screws seated perfectly for my clamping job, and the hex socket drive made tightening a breeze even in a tight spot.

Olivia ★★★★★

Picked up these set screws for a shaft clamping job and the hex socket drive made installation quick and precise. The thermal black oxide finish adds a nice touch of corrosion resistance.
