براغي M24-3 X 130mm رأس أسطواني | محرك سداسي داخلي | خيط جزئي | فولاذ سبائك فئة 12.9 أكسيد أسود حراري (10 / عبوة)

I needed heavy-duty fasteners for a jig assembly and these M24-3 x 130mm screws handled the torque beautifully without stripping. The black oxide finish feels solid and the partially threaded shank made alignment precise.

The hex socket drive seated perfectly with my torque wrench, and the black oxide finish handled a week of shop grime without a spot of rust. Class 12.9 stiffness is obvious the moment you tighten them down—these aren’t going to strip on me.

Finally got these mounted on a heavy-duty jig and the hex socket drive made installation a breeze with no stripping. The black oxide finish feels durable and the partially threaded design is perfect for alignment.
