براغي رأس سداسي 9/16-12 × 2-3/4 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئيًا (25 / عبوة)

These fit perfectly on the equipment I'm repairing, and the partially threaded design gives me the right grip for the torque specs. The hex heads haven't stripped even with a wrench at full effort.

The yellow zinc coating on these grade 5 bolts looks even better in person, and the partially threaded design made lining up the nut a breeze on my equipment assembly.

These bolts threaded in smoothly without binding, and the hex head gave my socket wrench a solid grip. Used them to repair my tractor's mower deck, and they held tight under vibration. Exactly what I needed for heavy-duty equipment.
