Michael G. ★★★★★

The threading stops exactly where it should, so these seat perfectly in my fixture plates without bottoming out. The black oxide finish feels slick and uniform, and all 100 came out of the box with clean, burr-free hex sockets. These are going straight into my tooling rotation.

Victoria ★★★★★

I needed longer bolts for a jig I was building, and these 120mm screws fit perfectly in the threaded holes. The partially threaded shank gives just the right amount of grip without needing a spacer.

Julian C. ★★★★★

The black oxide finish on these 120mm screws matches my jig perfectly and the hex drive made installation a breeze with no cam-out issues. I’ve used a few from the pack already and they hold torque well.
