براغي رأس كبس M2-0.4 × 10 مم | محرك سداسي مسطح الرأس | ملولبة بالكامل | فولاد سبائكي فئة 12.9 أكسيد أسود حراري (400 / عبوة)

I've been looking for precise M2 hardware for a robotics jig, and these 10mm flat head screws fit perfectly without any wobble. The hex socket drive takes an Allen key cleanly, and the class 12.9 alloy steel feels tougher than most other screws I've used.

The black oxide finish is consistent across all 400 pieces, and the hex socket drive seated perfectly in my tooling fixture. Feels like solid 12.9 alloy steel, not the cheap stuff that strips out.

Used these M2s on a small jig and the 12.9 alloy steel feels seriously tough for the size, plus the black oxide finish looks clean. The threaded length is uniform across all 400 pieces, which saved me a ton of sorting time.
