Richard ★★★★★

The black oxide finish on these screws looks professional and resists rust, which is perfect for my tooling setup. Hex drive makes installation a breeze.

George ★★★★★

Got these for a jig I’m building, and the hex socket drive makes them a lot easier to tighten in tight spots than a standard Phillips. Threads cut clean and the black oxide finish looks sharp against the steel.

George ★★★★★

The black oxide finish on these screws looks clean and professional, and the hex socket drive made installation with my allen wrench effortless. I used them to assemble a custom jig and every thread seated perfectly without any binding. Exactly the precision I needed for this project.
