براغي رأس سداسي M30-3.5 X 190mm | فولاذ درجة 8.8 عادي | ملولبة جزئياً (3/عبوة)

These bolts cinched down tightly with just a socket wrench, and the 3.5 thread pitch held firm on our press frame without stripping.

I was a little worried about the thread pitch being too fine for my equipment, but the 3.5mm pitch matched perfectly and the hex head seated firmly with zero wobble.

The partially threaded design made cinching down our press frame a lot easier since the smooth shank takes the shear load without chewing up the threads. These M30 bolts are seriously hefty, and the hex head grabbed perfectly with my impact socket. Three in a pack is a solid deal for the price.
