براغي رأس سداسي ثقيل مقاس 5/8-11 × 1-3/4 بوصة | صناعة أمريكية | فولاذ A307 درجة B عادي | خيط كامل (110 / عبوة)

The threading on these screws is so consistent that every one of them spun on smoothly without any binding. I used them for mounting a heavy piece of shop equipment, and the 5/8-11 size and A307 Grade B steel give me total confidence in the hold.

We've been using these bolts for heavy equipment assembly and the threading is clean and consistent all the way down, which saved us time. The hex head fits a standard wrench perfectly with no slipping.

Got these for a machinery repair on a Friday afternoon, and they fit perfectly without any wrestling or re-tapping. That 110-count pack means I've got spares for the next job, and the fully threaded length gave me solid grip through the whole joint.
