براغي رأس مقبس M6-1 X 70 مم | رأس مسطح مع محرك سداسي | ملولب جزئيًا | فئة 12.9 سبائك فولاذية مؤكسدة حرارياً باللون الأسود (200 / عبوة)

I needed longer bolts for a jig I was building and these M6-1 x 70mm socket cap screws fit perfectly. The 12.9 alloy steel feels incredibly sturdy, and the black oxide finish looks great against the metal parts.

The partial threading on these 70mm bolts grabbed perfectly when I set them in my jig, and the hex socket drive made tightening in tight spots a breeze. The 12.9 alloy steel feels seriously solid for the price, and the black oxide coating hasn't scratched off during handling.

The black oxide finish on these M6 bolts looks sharp and the hex socket drive grabs cleanly without stripping. I've got about half the box into my jig builds now, and the partially threaded length seats perfectly for clamping. Exactly what I needed for precision work.
