براغي ذات رأس سداسي M30-3.5 × 100 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة بالكامل (5 / عبوة)

I needed something heavy-duty for a large assembly jig, and these M30-3.5 x 100mm hex head cap screws fit perfectly. The zinc plating looks clean and the class 8.8 steel feels solid under a wrench. Threads were smooth all the way down.

Used these fully threaded hex bolts to secure a heavy machine base, and the Class 8.8 steel held up perfectly under torque. The zinc plating already looks clean and rust-free after a week in a damp shop.

The zinc plating on these M30 bolts looks clean and even, and the fully threaded length made alignment in our jig a breeze. They’ve held up fine under repeated assembly and disassembly without any galling.
