براغي رأس سداسية ثقيلة 5/8-11 × 1-1/2 بوصة | صناعة أمريكية | A307 درجة B فولاذ عادي | خيط كامل (120 / عبوة)

These threads cut clean and the plating is consistent across all 120 pieces, which saved me a ton of sorting time. Went through a whole crate of them for a trailer frame job and didn't have a single one fight the die.

Bought a full box for a machinery rebuild and used about thirty so far, every single one threads on smooth and the fully threaded length gives you plenty of grip. The A307 grade B steel feels solid, not the soft junk you get elsewhere. Just wish they sold smaller quantities, but for the price per pi

Well the hex drive seated perfectly without slipping, which is what I needed for a tight assembly. These bolts feel solid and the threads cut cleanly into my tap.
