براغي ماكينة M4 × 12 مم | رأس مسطح فيليبس | فولاذ مطلي بأكسيد أسود (2000 / عبوة)

I’ve been using these screws for mounting metal conduit brackets, and the black oxide finish has held up perfectly with no signs of corrosion after a few weeks. The flat head sits flush against the surface, which makes for a clean, professional look.

Got these to mount some circuit boards in a project enclosure, and the 12mm length is perfect for grabbing into standoffs without poking through. The flat head sits flush, and the whole bag of 2000 feels like a lifetime supply.

The black oxide finish on these M4 screws looks great and holds up nicely during assembly—no rust spots after handling. The flat heads sit flush in the enclosures I’m building, which gives a clean, professional finish.
