Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas ★★★★★

Had to mount a small control panel inside an enclosure and the undercut head sits perfectly flush, saving me from having to counter-sink every hole. These bit nicely into the threaded standoffs without stripping.

James V. ★★★★★

The Phillips drive bit into the steel perfectly without stripping, even when I was working in tight spots. The zinc plating on these screws looks clean and should hold up well against moisture.

Isabella ★★★★★

Used these to mount a small control panel to an aluminum frame, and the undercut head seated perfectly flush every time. The zinc plating looks clean and the threads caught smoothly with no cross-threading across all 2000 pieces.
