براغي رأس مقبس M16-2 X 25mm | محرك مقبس سداسي | خيط كامل | سبائك فولاذية فئة 12.9 أكسيد أسود حراري (50 / عبوة)

I was a bit worried about ordering hardware online, but these M16 bolts are impressively precise. The hex socket drive fits my tool perfectly, and the black oxide finish gives them a sturdy, professional look for my jig build.

Threaded all the way down to the shoulder, these seated flush in my jig without any binding. The black oxide finish wiped clean easily, and the hex socket gripped without stripping—solid fasteners for a precision assembly.

I needed some high-strength fasteners for a jig setup, and these 12.9 alloy steel screws have the perfect bite. The black oxide finish looks clean and should resist rust in my shop.
