مسامير رأس سوكيت M8-1.25 × 22mm | محرك سوكيت سداسي | ملولبة بالكامل | فولاد سبائكي فئة 12.9 معالجة بأكسيد أسود حراري (300 / عبوه)

The black oxide finish on these screws looks sharp and resists oil stains well during assembly. Each one drove smoothly into tapped holes without any binding, and the hex socket held the driver securely.

I needed a batch of strong, precision bolts for a jig I'm building, and these M8 black oxide screws are exactly what I was hoping for. The 12.9 alloy steel feels incredibly solid, and a full package of 300 gives plenty of spares for future projects.

The hex socket drive grabs the Allen key perfectly with zero stripping, even after torquing these down on a jig build. The black oxide finish looks clean and the fully threaded length makes alignment easy. Whole box measured consistent at 22mm, which is exactly what I needed for precision work.
