Mia ★★★★★

The knurled cup point on these screws really gripped the shaft on my lawn mower pulley without slipping. They’re exactly 1 inch long as described, and the black oxide finish looks clean and professional.

Victoria ★★★★★

I needed a screw that wouldn’t loosen under vibration for a clamping application, and the hex socket drive on these lets me torque them down securely. The thermal black oxide finish also looks clean and seems to resist fingerprints better than I expected.

Amelia ★★★★★

The knurled cup point bites into the shaft way better than a plain cup, so my clamp hasn’t budged under vibration. The thermal black oxide finish also made them easy to grip with an Allen key right out of the box, no oil residue fuss.
