Customer Reviews (4.6 / 5 · 5 reviews)

Madison ★★★★★

The hex socket drive grips the Allen key perfectly with zero stripping, and the 12.9 alloy steel feels seriously tough for such tiny fasteners. I've used about half the pack on a jig build and not a single one has deformed or shown any wear.

Eli ★★★★★

The black oxide finish on these M2 screws is holding up perfectly in my tooling jig, even with daily adjustments. The hex socket drive engaged cleanly without stripping, which I appreciated for such small fasteners.

Eli O. ★★★★★

Needed some small screws for a jig project and these M2 black oxide bolts fit perfectly. The hex socket drive makes them easy to tighten without stripping, and the class 12.9 steel feels really tough.
