براغي رأس سداسي M30-3.5 × 75 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة بالكامل (5 / عبوة)

I needed these for a heavy machinery repair, and the fully threaded design made them perfect for securing thick plates together. The zinc plating already looks like it will resist rust well in our shop environment.

The hex head gave my socket wrench a solid grip without slipping, and the zinc coating looks clean. Used them to secure a heavy machine base plate, and they seated perfectly in the pre-tapped holes.

These bolts threaded smoothly all the way through the mounting plate, which saved me a lot of time. The zinc coating seems durable and the hex head gave my socket wrench a solid grip.
