براغي رأس سداسي 5/8-11 × 4 بوصة | فولاذ درجة 8 مطلي بالزنك | خيط جزئي (100 / عبوة)

The hex head took a socket wrench perfectly without any rounding, and the zinc coating looks clean and corrosion-resistant. I used these to bolt down a heavy-duty hitch plate, and the grade 8 steel feels rock solid under torque. Exactly what I needed for industrial assembly.

The partially threaded design made it easy to get these started in my tractor's attachment bracket, and the hex head gave my socket wrench a solid grip. I went through all 100 bolts without a single stripped thread or damaged finish.

These bolts threaded smoothly into my tractor's frame with no binding, and the zinc coating looks like it'll resist rust well. The hex heads gave my socket a solid grip for torquing them down to spec. Perfect fit for the heavy equipment repair I needed them for.
