براغي رأس مقبس M6-1 × 35 مم | رأس زر بمحرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 بأكسيد أسود حراري (400 / عبوة)

The hex drive on these M6-1 screws works perfectly with my standard Allen keys—no stripping or slipping like cheaper ones. The black oxide finish looks clean and professional on the jig I built.

These M6-1 x 35mm screws are precisely what I needed for my jig setup—the thermal black oxide finish seems really durable and they threaded smoothly into my fixture plate. I appreciate the consistent quality across the whole 400-piece package.

Picked up a pack for a custom jig build and the Class 12.9 strength really delivers — these screws didn't strip or deform under heavy clamping. The black oxide finish also seems durable and won't rust easily.
