Customer Reviews (4.0 / 5 · 5 reviews)

Penelope ★★★★★

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.

Samuel ★★★★★

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.

Daniel ★★★★☆

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.
