براغي رأس مقبس M8-1.25 × 160 مم | محرك سداسي | جزئي الخيط | فولاذ سبائكي فئة 12.9 مع أكسيد أسود حراري (50 / عبوة)

Used a few of these to replace stripped bolts on a milling machine jig. The black oxide finish is a nice touch and the 12.9 grade handles torque without any sign of stress. Exactly what I needed for a snug fit in a tight spot.

Finally got around to mounting some heavy jig fixtures with these M8 socket caps and the 12.9 alloy steel feels seriously tough. The black oxide finish handled a bit of oil without any signs of wear, and the hex drive seated perfectly every time.

I've been using these screws to assemble a jig for my workshop, and the 160mm length was exactly what I needed. The hex socket drive makes installation quick with a standard Allen key.
