براغي رأس سداسي 5/8-11 × 3-1/2 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (25/عبوة)

I needed a couple of these for a stubborn piece of farm equipment, and the hex head made it easy to get a socket on them. The yellow zinc finish seems tough, and the partial threading gave me a clean grip without binding up.

Needed these for a heavy equipment repair and the grade 5 steel with the yellow zinc held up perfectly under torque. The partial threading made alignment a breeze.

The hex head gave my socket a solid grip, and the yellow zinc coating has a nice, even finish that resists rust well. These grade 5 bolts are holding up perfectly on my heavy equipment assembly project.
