M18-1.5 X 40mm براغي رأس سداسي | فولاذ فئة 10.9 مطلي بالزنك | ملولبة بالكامل (25 / عبوة)

Used these to secure a heavy-duty conveyor frame at work and the 10.9 grade held up perfectly under full torque. The zinc plating was even and clean, no burrs on the threads straight out of the pack.

Put these on a tractor PTO shaft guard bracket and the class 10.9 strength handled the torque perfectly. The zinc plating seems durable and the full thread gave me plenty of grip.

The zinc plating on these M18 bolts looks clean and even, and the threads cut into the steel nut without any binding. Fully threaded means I could trim them to length for a tight fit on my equipment stand, and the hex head grabbed firmly with a socket.
