Richard W. ★★★★★

Used these to build a new jig for our CNC table and the threads engaged perfectly every time, no cross-threading or binding even when cinched down tight. The thermal black oxide left a slick, consistent finish that wiped clean after cutting fluid splashed on them, which I appreciate since I hate rus

Mia ★★★★★

The black oxide finish on these took my tooling setup to another level—they thread in smooth as butter and the hex socket grabs perfectly with my Allen key. Fifty pieces for this price means I've got stock for every fixture I'll ever make.

Isabella G. ★★★★★

I was building a new jig for my milling machine and these black oxide screws fit perfectly in the tapped holes without any binding. The 5/8-11 threads are clean and consistent across all 50 pieces in the package.
