Customer Reviews (4.2 / 5 · 5 reviews)

James ★★★★★

These M12 bolts came out of the package with a perfectly even black oxide finish, and the hex socket drive fit my Allen key with zero slop. Used them to re-secure a jig table and they torqued down cleanly without stripping.

Zoe P. ★★★★★

The flat heads sit perfectly flush in my tooling plates—no snagging at all. The thermal black oxide finish has a nice matte look and seems to resist oil and grime well.

Riley Q. ★★★★☆

Installed these in a jig fixture at work and they seated perfectly without any wobble. The flat head sits flush like it should, which saved me from having to counterbore deeper. Only wish they came in a smaller quantity pack, but the price per piece is reasonable.
