براغي رأس سداسي 3/4-16 X 11" | صنع في الولايات المتحدة | سبيكة فولاذ درجة L9 زنك أصفر | ملولبة جزئياً (15 / عبوة)

These threaded in smoothly without any binding, and the partially threaded shank gave me the grip I needed for a heavy equipment jig. The hex heads held up perfectly under high torque with my impact wrench.

The yellow zinc coating is even and tough—no chips after torquing these down hard on a jig base. Threads ran clean into a tapped hole without any galling, and the partial thread gave me just the grip I needed for the spacer stack.

Put these on a heavy-duty press frame I’m rebuilding, and the threads were clean enough to run down by hand for the first inch. The partially threaded shank gave me plenty of grip without having to cut down a fully threaded bolt.
