Elizabeth ★★★★★

I was a little worried about getting 600 of a size I’d never tried before, but the black oxide finish on these #4-40 screws gives them a nice, consistent look on my metal panels. They drive smoothly without snapping, and the flat head countersinks cleanly into my enclosure holes.

Carter ★★★★★

The flat head sits flush perfectly when securing metal panels, which was exactly what I needed. The Phillips drive grabbed nicely without camming out during installation.

Brian Y. ★★★★★

The black oxide finish on these screws grips the driver bit nicely without slipping. I used a whole bag for mounting control panels and every single one threaded cleanly with no duds.
