براغي رأس سداسي 1/2-13 × 9-1/2 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (6 / عبوة)

The hex heads on these bolts gripped my socket ratchet perfectly, and the yellow zinc finish looks clean and corrosion-resistant. I just finished rebuilding a piece of farm equipment with them.

The partially threaded design made installation much easier, as I could start the nut by hand before tightening with a socket. These grade 5 bolts feel solid and the hex head handled torque well without slipping.

The yellow zinc finish on these bolts held up perfectly even in my slightly damp shop, no rust after a week. The partially threaded design made them much easier to start in tight spots on my assembly jig.
