براغي رأس سداسية M36-4 × 180 مم | فولاذ عادي فئة 10.9 | خيط جزئي (1 / عبوة)

Needed these for a heavy-duty fixture on an assembly table and the 180mm length gave me just enough thread grip. The partially threaded design made alignment a breeze compared to full-thread bolts.

Had to torque these pretty hard during a heavy equipment repair, and the hex head held up perfectly without any rounding. The partial threading made alignment a lot easier than fully threaded bolts I've used before. Exactly the kind of sturdy fastener you need for industrial work.

Went together exactly as hoped on a big frame jig I’m building. The 180mm length gave just enough thread engagement for the heavy nuts I needed, and the Class 10.9 steel feels seriously solid.
