براغي رأس كبس M16-2 × 100 مم | محرك سداسي مسطح الرأس | خيط جزئي | فولاذ سبيكة فئة 12.9 مع أكسيد أسود حراري (25 / عبوة)

The black oxide finish on these screws is holding up well in my machine tool setup, no signs of wear after a week of adjustments. The hex socket drive grips perfectly without stripping, and the partial threading makes alignment a breeze.

The black oxide finish really holds up well during assembly work. I used a full pack mounting heavy tooling brackets, and the fit in the hex socket was precise every time. These feel much more solid than standard hardware store bolts.

The partially threaded design on these M16 bolts made all the difference for my jig setup, providing a precise fit where I needed it. The black oxide finish looks clean and seems durable for shop use.
