براغي رأس مقبس M5-0.8 X 22mm | محرك مقبس سداسي | كامل الخيط | فولاذ سبائك فئة 12.9 مؤكسد أسود حراريًا (600 / عبوة)

The hex socket drive sits perfectly flush, and the black oxide finish on these 12.9 alloy screws gives them a professional look. I used a full pack for a tooling jig, and every single one threaded smoothly without any binding.

Needed fasteners for a precision assembly project, and these M5s fit perfectly with their class 12.9 strength. The black oxide coating made them easy to handle without any glare. A solid choice for reliable, tight threading in machinery work.

Installed these in a custom jig for a robotics project and they seated perfectly without any wobble. The black oxide finish gave them a nice grip during tightening, and the 12.9 alloy steel feels plenty strong for the torque I applied.
