براغي رأس سداسي M30-3.5 X 300mm | فولاذ فئة 8.8 مطلي بالزنك | ملولب جزئيًا (1/عبوة)

The hex head gave my socket wrench a solid grip without slipping, and these M30 bolts fit perfectly into my press frame. They’re hefty and the zinc coating looks like it’ll resist rust well.

Threads cut clean and the partial thread left plenty of grip for the machine frame I bolted down. The zinc coating looks even, no flaking. These M30s are solid for the price.

I needed heavy-duty bolts for a press frame, and the 300mm length with the hex head made installation straightforward with a socket wrench. The zinc plating seems solid and the class 8.8 steel feels plenty robust for the job.
