Customer Reviews (4.6 / 5 · 5 reviews)

Violet H. ★★★★★

The black oxide finish on these screws looks sharp and held up fine during assembly on my jig fixture. All 100 threaded in cleanly with no binding, and the flat head seated flush every time. These are my go-to for precision work now.

Sophia L. ★★★★★

The black oxide finish on these screws slid into my milling fixture holes without any binding, and the hex socket drove smoothly with no stripping. For a hundred pieces at this grade, the fit and finish exceeded what I expected from a general-pack fastener.

Miles ★★★★★

The black oxide finish on these screws looks sharp and consistent across the whole package, which matters for the jigs I'm building. The threads engaged smoothly on the first try, and the flat head seated flush without any wobble.
