براغي رأس سداسية M18-2.5 X 180mm | فولاذ فئة 8.8 مطلي بالزنك | سنون جزئية (10/عبوة)

The threads on these are clean and the zinc coating is even, so they tightened smoothly without any binding. I used them to bolt down a heavy gearbox and the 180mm length gave plenty of grip.

I needed a heavy-duty fastener for a jig assembly and the hex head made tightening with a socket wrench effortless. The zinc plating on these 8.8 steel screws looks durable and clean.

The partial threading on these M18 bolts made aligning the motor mount much simpler than fully threaded ones I've used before. The hex head gave my socket a solid grip, and the zinc plating looks clean and hasn't shown any rust after a week outdoors.
