Customer Reviews (5.0 / 5 · 5 reviews)

Ella ★★★★★

Needed some for a jig I'm building and the thermal black oxide finish looks great and feels sturdy. The hex drive seated cleanly without stripping, which made assembly a breeze.

Amelia K. ★★★★★

The flat head sits flush perfectly on my precision assembly jig, and the black oxide finish looks professional. I’ve already used a dozen without any stripping or fit issues.

Leo ★★★★★

Needed to fasten a bracket to a jig plate, and these flat head screws seated perfectly flush. The black oxide finish gives them good corrosion resistance for the shop environment.
