براغي رأس سداسية 7/16-20 × 2 بوصة | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (50 / عبوة)

I needed a solid bolt for a tractor hitch repair, and the hex head on these made torquing them down easy with a socket. They threaded smoothly into the existing nut and the yellow zinc finish hasn't shown any rust after a couple weeks of outdoor use.

The hex heads fit my socket wrench perfectly, and the yellow zinc coating looks clean and corrosion-resistant. These are exactly the right size for securing a heavy machine guard I'm rebuilding.

Used a few of these to repair a piece of farm equipment, and the hex head was easy to grip with a socket even in a tight spot. The yellow zinc coating seems durable and hasn't shown any corrosion after a week in the rain.
