1"-14 × 9-1/2" براغي رأس سداسية | صناعة أمريكية | فولاذ درجة 8 أصفر زنك (15 / عبوة)

Used these to rebuild a press at the shop and the threads are clean, no burs from the get-go. The Grade 8 rating gives me peace of mind under heavy loads, and the yellow zinc finish hasn't shown any rust yet.

These bolts threaded perfectly into some heavy lifting brackets I was assembling, and the yellow zinc finish looks like it will hold up well in a shop environment. The 1"-14 thread cut cleanly without any binding, and the hex head gave my socket a solid grip for torquing them down.

Installed these on a large press jig at work and the Grade 8 steel held up perfectly under heavy torque. The hex head gave my socket wrench a solid bite without rounding.
