براغي رأس سداسية 5/16-18 × 7 بوصة | صناعة أمريكية | فولاذ درجة 8 مطلي بالزنك الأصفر (225 / عبوة)

I needed some long cap screws for a heavy equipment repair, and these 7-inch Grade 8 steel hex heads held up perfectly under the torque. The yellow zinc coating looks clean and seems tough, plus being made in the USA gives me confidence.

These bolts threaded through my tractor’s frame perfectly, and the hex heads held up under a lot of torque with my impact wrench. The yellow zinc coating looks consistent and clean across all 225 pieces.

Finally, bolts that are actually the full 7 inches and thread cleanly without binding. The Grade 8 yellow zinc finish looks solid and should resist rust well for machinery use.
