براغي رأس سداسي M30-3.5 × 120 مم | فئة 10.9 من الصلب مطلي بالزنك | ملولبة جزئيًا (15 / عبوة)

I used these for mounting a heavy motor mount and the hex head gave me a solid grip with my socket wrench. The zinc finish looks clean and hasn't shown any rust after a week of outdoor exposure.

These partially threaded 120mm screws held up perfectly when I was assembling a heavy-duty machine frame. The zinc plating gave them a nice even finish and I had no issues with the hex head stripping under my torque wrench.

The hex heads on these bolts gave my wrench a solid grip when tightening equipment, and the partial threading made alignment a breeze. Zinc coating should keep them from rusting in my shop, which is exactly what I needed for heavy-duty assembly.
