براغي رأس سداسي 1/2-13 × 2-3/4 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (50 / عبوة)

Grabbed these for a trailer hitch repair and the partially threaded shank made alignment much easier than dealing with full threads. The yellow zinc coating looks like it'll handle some weather too.

The hex heads on these 50-pack bolts seated perfectly in my socket wrench without any slipping. Used them to mount a motor bracket and the yellow zinc finish held up well against minor shop grime.

The partial threading on these 1/2-13 bolts made a big difference for my equipment build, letting me tighten securely without fighting the full length. They fit perfectly in a standard socket and the hex heads didn't strip even under heavy torque.
