براغي رأس كبس M4-0.7 × 8 مم | محرك سداسي مسطح الرأس | كامل الخيوط | درجة 10.9 سبيكة فولاذ معالجة حرارياً أسود أكسيد (600 / عبوة)

I've been using these in a jig I built for drilling precise holes, and the flat head sits perfectly flush every time. The black oxide finish looks great and hasn't worn off even after tightening several screws. A solid buy for any tooling project.

These little M4 screws are perfect for my jigs, the hex socket drive grips well and the 10.9 alloy steel feels plenty tough for precision assembly. I’ve already gone through a good chunk of the 600-pack and every single one threads cleanly without any stripped heads.

Installing these in a tight jig setup was a breeze — the hex socket grabs perfectly even with a cheap driver. Black oxide finish looks clean and should resist rust better than plain steel.
