براغي رأس سداسي M36-4 × 220 مم من الفولاذ الصلب فئة 8.8 عادي | ملولبة جزئيًا (2 / عبوة)

I had to torque these down to 450 Nm, and the hex head held up perfectly without any rounding. The class 8.8 steel feels solid for heavy equipment assembly.

Fitting these into a heavy equipment jig took some muscle, but the hex head grabs a socket perfectly and the 220mm length gave me plenty of thread engagement. The class 8.8 steel feels plenty rigid for the load, and having two in the pack saved me a second trip.

The partially threaded shank on these M36 bolts made aligning the machinery base much easier than fighting a fully threaded rod. They seated firmly with a socket and the Class 8.8 steel feels robust for heavy equipment use. Exactly what our industrial assembly needed.
