Jason H. ★★★★★

The black oxide finish on these screws gives them a nice, uniform look that resists glare in the shop. They fit perfectly into my jig’s tapped holes without any binding, and the low head profile cleared a tight shroud clearance.

Ellie ★★★★★

I was a little worried about the hex socket stripping on a low head screw, but these have held up perfectly in my jig fixtures. The black oxide finish gives them a nice, consistent look and they seat flush without any wobble.

Joseph N. ★★★★★

The threads on these 5/16-24 screws are cut clean enough that they seated smoothly in every hole I tried, and the black oxide finish looks sharp against my jig frames. For a hundred pieces at this price, the alloy steel feels sturdy without any burrs I had to chase with a file.
