براغي رأس سداسية 1-1/4-7 × 4 بوصة | صناعة أمريكية | درجة 8 فولاذ مطلي بالزنك الأصفر (20 / عبوة)

I needed a set of 1-1/4-7 bolts for a heavy farm repair, and these Grade 8 hex heads fit the impact socket perfectly with no wobble. The yellow zinc finish looks uniform and the threads engaged smoothly right from the start.

I've been through three sets of cheaper bolts on my press brake and these are the first ones that haven't walked loose after a week of hard use. The yellow zinc coating looks factory-fresh even after getting soaked in coolant, and the hex heads grab a socket cleanly every time. Threads are cut perfe

These 4-inchers hit the mark for heavy equipment repair. The Grade 8 yellow zinc finish is holding up perfectly on my trailer hitch bolts. You can tell they're USA made, the threads cut clean every time.
