براغي رأس مقبس M24-3 × 125 مم | رأس مسطح محرك مقبس سداسي | جزئي الخيط | فولاذ سبائكي فئة 12.9 أكسيد أسود حراري (5/عبوة)

The flat head design sits perfectly flush on my jig plate, and the black oxide coating gives them a nice corrosion-resistant finish for heavy use.

These 12.9 grade screws fit perfectly into my jig's threaded holes, and the black oxide finish looks like it will resist rust well. The flat head sits flush without any wobble, which was exactly what I needed for a precise assembly. I'm really impressed with the quality for the price.

The hex socket seated perfectly on my torque wrench with zero wobble, and the black oxide finish feels properly slick. Threads ran smooth through the tapped hole on my precision assembly, and the 12.9 hardness gives me full confidence under load.
