Customer Reviews (4.2 / 5 · 5 reviews)

Lily R. ★★★★★

Used a full pack on a custom jig and every single one seated clean without stripping the hex drive. The 40mm length was exactly right for my fixture, and the black oxide coat survived a week of shop grime without a speck of rust.

Evelyn E. ★★★★★

The thermal black oxide finish on these screws gives them a nice, non-reflective look that blends well with dark machinery parts. I used them for a jig build and the hex socket drive made installation easy and secure.

Samuel ★★★★★

Used a few of these M4 screws to secure a jig I’m building, and the black oxide finish feels tougher than standard hardware store stuff. The hex socket drive seated perfectly with my allen key, no stripping.
