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

Zinc coating is even and clean, threading grabbed smoothly with no galling on the first try. These hex heads seat nicely with a socket, and the partial thread gives just the right grip for the heavy equipment frame I was bolting back together.

The partially threaded shank on these 9/16-12 bolts grabbed exactly where I needed it to for a jig setup, and the hex heads made wrench work a breeze. Twenty-five in the pack for this grade feels like a solid deal, and they came out of the box with a clean, uniform zinc coat.

The yellow zinc finish is holding up nicely after a week of assembly work—no chipping around the hex heads when I torqued them down. Threads were clean and caught true right out of the package, which made for a quick install on my equipment frame.
