براغي رأس كبس بمقبس M6-1 × 65 مم | محرك مقبس سداسي | خيط جزئي | سبيكة فولاذ فئة 8.8 أكسيد أسود حراري (200/عبوة)

Pulled a few of these out for a tooling fixture and the hex socket drive made tightening them in tight spots so much easier. The black oxide finish looks solid and hasn't chipped during installation.

Used a handful of these for a jig I’m building and the black oxide finish looks clean and adds some corrosion resistance. The hex socket drive made them easy to tighten without stripping, and the 65mm length was perfect for my application.

Just swapped out the cheap bolts on my milling machine clamp set with these 65mm ones — the black oxide finish already feels way more durable than the zinc-plated junk I had before.
