براغي رأس سداسي 1/2-13 × 7/8" | صناعة أمريكية | فولاذ درجة 8 زنك أصفر | خيط كامل (50/عبوة)

The yellow zinc coating on these bolts is holding up great against rust in my outdoor equipment, and the Grade 8 steel gives me confidence for heavy-duty use. They seated perfectly with a socket wrench on my tractor attachment, no stripping issues at all.

These bolts fit perfectly into a drilling rig jig I'm building, and the yellow zinc coating looks like it'll hold up way better than standard black oxide. The hex heads grab my socket firmly without any rounding.

Needed some heavy-duty bolts for a shop press rebuild, and these grade 8 screws with the yellow zinc coating felt hefty right out of the package. The fully threaded shank made alignment quick, and every one of the 50 pieces seated cleanly with a socket wrench.
