Customer Reviews (4.8 / 5 · 5 reviews)

Amelia G. ★★★★★

The black oxide finish on these screws is way more consistent than other packs I've tried, and the hex drive engages perfectly with my 5mm Allen key. Used a dozen to secure a tooling fixture and every single one threaded smooth without any binding.

Isabella ★★★★★

Installed these in a jig for a production run and the hex drive didn't strip at all, which was my biggest worry. The alloy steel feels noticeably tougher than standard hardware.

Victoria F. ★★★★★

The black oxide finish held up perfectly against oil and chips in my lathe—no rust after a full week of use. Threads started cleanly into every tapped hole without binding. Exactly what I needed for fixture builds.
