براغي رأس سداسية 3/8-16 × 7-1/2 بوصة | صناعة أمريكية | فولاذ درجة 8 زنك أصفر (20 / عبوة)

The yellow zinc coating on these Grade 8 bolts is much thicker than I expected, so they should hold up well against rust in my shop. Threads cut smoothly into a tapped hole without binding.

I needed some beefy bolts for a heavy equipment jig, and these Grade 8s fit perfectly with no slop in the threads. The hex heads seated cleanly with a socket, and the yellow zinc finish looks like it’ll hold up well.

These bolts worked perfectly for a heavy rack repair in my shop—the threads were clean and threaded in smoothly with no binding. Only gave 4 stars because I wish they came individually wrapped or with a small parts bag, but the quality of the steel itself is solid.
