براغي رأس سداسية 5/8-11 × 7-1/2 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئيًا (10 / عبوة)

I needed heavy-duty bolts for a press rebuild and these grade 5 screws held up perfectly under torque. The yellow zinc coating looks consistent and hasn't chipped during installation.

The partial threading on these bolts made aligning the equipment mounts so much easier, and the yellow zinc finish looks sharp. They're solid Grade 5 steel and the hex heads worked fine with my impact wrench, no stripping at all.

The hex heads grabbed my socket perfectly without any rounding, and the yellow zinc finish looks clean against the equipment frame. Threads ran smooth right up to the unthreaded shank, which gave me the precise grip I needed for alignment.
