براغي رأس كبس M6-1 × 18 مم | محرك سداسي | كامل الخيوط | فولاذ سبيكة فئة 12.9 مؤكسد أسود حراري (600/عبوة)

I replaced all the M8 bolts on that jig table with these, and the 12.9 grade is noticeably tougher against stripping. The black oxide finish also seems more consistent than cheaper sets I've used before.

I was looking for high-strength fasteners for a jig I’m building, and these M6 socket cap screws with the 12.9 alloy steel feel incredibly solid. The thermal black oxide finish looks clean and seems like it’ll hold up well in my shop.

Pulled these out of the box and they're exactly what I needed for mounting brackets—the hex socket drive made installation quick with no stripped heads. The black oxide finish looks clean and professional on the assembly.
