Zoe H. ★★★★★

The black oxide finish on these screws held up perfectly during assembly—no galling or binding in the threaded holes like I've seen with cheaper plating. They fit the jig block snugly and the hex drive seated without any wobble. Exactly what I needed for a precision tooling project.

John ★★★★★

I've been hunting for a while for an exact 2-1/2" length in this thread size, and these fit perfectly for my jig setup. The thermal black oxide coating looks uniform and hasn't chipped even after a few hard torques.

Steven ★★★★★

The black oxide finish on these #10-32 socket cap screws is a nice touch, making them look great in my jig setup. They threaded smoothly into tapped holes, and the hex drive gripped perfectly without any stripping. Exactly what I needed for a precision assembly project.
