Jason Y. ★★★★★

Pulled these out of the package and the yellow zinc finish is way more even than I’m used to seeing on bulk hardware. The partial threading grabbed just where I needed it for a jig I’m rebuilding, and the hex head seated cleanly with a socket. For the price per piece, these are a solid deal.

Olivia J. ★★★★★

These bolts fit perfectly into my equipment assembly jig, and the yellow zinc coating feels durable. The partially threaded shaft made aligning the nut much faster than fully threaded options I've used before.

Ryan ★★★★★

I needed some tough 4-inch bolts for a heavy equipment repair, and these Grade 5 hex head screws threaded in smoothly without any binding. The yellow zinc coating looks decent and the 50-count package was more than enough for my job.
