Customer Reviews (4.4 / 5 · 5 reviews)

Samuel P. ★★★★★

The partially threaded shank made aligning these bolts in steel beams so much easier, and the grip length was spot on. The galvanized finish feels thick and durable, perfect for outdoor use. I'm glad I finally found a quality bulk option.

Emma ★★★★★

The hot-dip galvanized coating looks really even and thick, so I'm confident these won't rust out on my trailer hitch project. The unthreaded grip section made aligning the bolt through the steel bracket much easier than dealing with a fully threaded one.

David ★★★★★

I needed a full box of these for a deck rebuild and the partially threaded shank saved me from having to use extra washers to get a snug fit. The hex heads grabbed perfectly with a socket wrench, and the hot-dip galvanizing looks tough enough to handle the elements.
