Customer Reviews (5.0 / 5 · 5 reviews)

Leo ★★★★★

The black oxide finish on these screws looks great and seems durable—no coating flaking off during installation. Worked perfectly for a jig I’m building, and the hex drive seated smoothly in the socket.

Scarlett V. ★★★★★

I was a bit worried about the fit, but the black oxide finish on these screws made threading them into my jig’s tapped holes much smoother than the bare steel ones I’ve used before. They’re holding firm under heavy use.

Samuel R. ★★★★★

These are the exact length I needed for a jig fixture I’m building, and the hex socket drive made tightening them in tight spots much easier. The threads were clean and seated perfectly without any binding.
