براغي رأس مقبس M8-1.25 X 35mm | محرك مقبس سداسي | كاملة الخيط | سبيكة فولاذ فئة 12.9 أكسيد أسود حراري (200/عبوة)

Perfect thread engagement every single time I've used them, and the hex socket drive bites firmly without any stripping. The thermal black oxide finish has held up great across multiple assemblies so far. For 200 pieces at this price, these are a solid buy for any jig or fixture work.

The black oxide finish on these M8 screws gives them a clean, professional look for jig builds. They threaded smoothly into my aluminum fixture without any binding, and the 12.9 alloy steel feels incredibly sturdy for the price per pack.

The hex socket drive on these screws fits my Allen key perfectly, and the black oxide finish looks clean on our jig setup. They threaded smoothly into tapped holes without any binding, which saved me time on a recent machining project.
