Customer Reviews (4.6 / 5 · 5 reviews)

Julian H. ★★★★★

The black oxide finish on these screws gives them a nice, uniform look, and the low head profile fit perfectly in my tight assembly jig. They drive smoothly with a hex key and held up well during torquing.

Amelia ★★★★★

Needed some low-profile fasteners for a tight assembly jig and these threaded in smooth without any binding. The black oxide finish actually held up better than I expected when I had to adjust the torque a couple of times.

Steven ★★★★★

I used these low head hex screws on a jig I was building, and the black oxide finish has held up well without any rust after a week in a damp garage. The threads are clean and the hex socket grips the wrench snugly, so they’re a solid choice for precision work.
