Customer Reviews (4.6 / 5 · 5 reviews)

Michael U. ★★★★★

The packaging was spot on—all fifty screws arrived clean and ready for my jig setup, not a single one with a damaged thread. The hex socket drive seated perfectly with my Allen key, and that thermal black oxide finish looks sharp against the steel.

Amelia ★★★★★

The black oxide finish on these screws is holding up well in my milling fixture so far. They thread cleanly into tapped holes without binding, and the hex socket drive lets me torque them evenly. Exactly what I needed for tooling.

Brian R. ★★★★★

Put these in a jig I'm building and the black oxide finish gives them a nice, consistent look alongside the other hardware. The threads started cleanly by hand every time, which saved me a lot of fiddling.
