براغي رأس سداسي ثقيل 5/8-11 × 1-3/4 بوصة | صنع في الولايات المتحدة | فولاذ A307 درجة B مطلي بالزنك | ملولبة بالكامل (175 / عبوة)

Finally got my shop press assembled and these bolts were exactly what I needed—the zinc plating seems thick and the threads cut cleanly into the steel. No stripped heads or wobble even under heavy torque.

I needed heavy-duty bolts for a tractor hitch repair, and the zinc plating on these looks perfectly even with no flaking out of the package. The threads caught smoothly in the nut on the first try, which saved me a lot of time.

The threads on these 5/8-11 bolts cut cleanly and didn't bind at all when I used them to secure a heavy-duty bracket. Solid A307 grade steel feels much tougher than the standard hardware store stuff. Exactly what I needed for a reliable industrial assembly.
