Customer Reviews (4.6 / 5 · 5 reviews)

Sophia G. ★★★★★

Finally found the right screws for my bench mill's power switch—the countersink head sits perfectly flush. Exactly the M4x20 size I needed, and the Phillips head didn't strip when I torqued it down.

Harper Y. ★★★★★

The Phillips slots on these M4x20s are cut clean and deep, so my driver bites instantly without stripping, and the flat head countersinks into the switch housing on my mill like it was machined for it.

Charlotte ★★★★★

The countersink head sits perfectly flush in the panel, which made installing the power switch on my mill a clean, professional-looking job. Threads cut smoothly into the existing nut without any binding.
