براغي رأس سداسي 5/16-18 × 2-1/4 بوصة | فولاذ درجة 5 زنك أصفر | خيط جزئي (100/عبوة)

The hex heads grabbed my socket wrench cleanly on the first try, and the yellow zinc finish looks tough enough for shop grime. I needed the partial threads to clamp two plates tight without bottoming out, and they did exactly that.

The partially threaded shank on these grade 5 bolts made alignment much easier when I was assembling a heavy-duty jig, and the yellow zinc finish seems tough enough to resist a few drops of oil. Exactly what I needed for the price.

I needed bolts that wouldn't strip easily under heavy torque, and the hex heads on these grip a socket perfectly every time. The yellow zinc coating looks clean and should resist rust well in my shop.
