براغي رأس مقبس M8-1.25 × 14 مم | رأس زر مع محرك سداسي | كامل الخيط | فولاذ سبائكي فئة 12.9 مع أكسيد أسود حراري (400 / عبوة)

Used a batch to secure some aluminum brackets to a steel frame for a jig, and every single screw threaded in smooth without any binding. The black oxide finish looks clean and resisted my oily fingers during assembly.

The hex drive fits my socket wrench perfectly, and the black oxide finish on these M8 screws looks like it will hold up well in my jig setup. I bought a full bag of 400 to stock my shop and every single one threaded smoothly into the tapped holes.

I was pleasantly surprised by the uniform black oxide finish on every screw in the bag — no scratches or bare spots. They seated perfectly in my jig threads without any binding. Exactly the quality I needed for tooling work.
