Customer Reviews (4.8 / 5 · 5 reviews)

William ★★★★★

The thermal black oxide finish on these screws is a nice touch—it makes them resist rust much better than the plain steel ones I've used before. The hex drive seated perfectly with my hex key, and they held tight in a precision assembly without stripping.

William ★★★★★

Used these on a jig I was building and the black oxide finish really held up against minor scuffs during assembly. They threaded smoothly and seated flush with no cross-threading issues.

Sophia ★★★★★

The black oxide finish has that deep, even look that tells you these were coated right, and they seated into my jig without any binding. For the price per piece, these are solid enough that I don't think twice about using them in a precision fixture.
