Sebastian ★★★★★

The black oxide finish on these screws looks great and doesn't show fingerprints like some other fasteners I've used. They fit perfectly into the tapped holes on my project and the knurled cup point holds really securely.

Violet A. ★★★★★

The hex socket drive grabbed the threads cleanly on the first try, and the thermal black oxide finish gives them a nice, uniform grip in the tapped hole. I've used cheaper set screws that stripped out, but these 100 pieces feel solid for the price.

Sophia ★★★★★

The knurled cup point on these set screws really bites into the shaft, so nothing slips once they're tightened. Perfect for holding a pulley in place on a small motor I was building.
