Customer Reviews (4.4 / 5 · 5 reviews)

Jason ★★★★★

Used these on a trailer hitch mount where the unthreaded grip length was exactly what I needed to keep things tight. The zinc coating has held up fine through some wet weather so far.

Sophia S. ★★★★★

I needed some bolts for a machinery repair where the grip length was critical, and these 5/16-18 hex heads fit the unthreaded shank requirement perfectly. The zinc plating seems consistent and corrosion-resistant, though the package of 200 is almost too many for my small workshop.

Emily ★★★★★

These bolts fit perfectly into my frame jig, and the unthreaded grip length made aligning everything much easier. The zinc coating looks clean and adds a nice layer of protection. I'm really happy with the quality for the price.
