Natalie C. ★★★★★

I needed corrosion-proof hardware for a saltwater dock repair, and the 316 stainless steel on these carriage bolts is holding up perfectly. The square neck grabbed the wood tightly on the first try, so I didn't have to hold the head while tightening the nut.

Hannah W. ★★★★★

Needed replacements for some galvanized ones on a dock repair and these 316 stainless ones went in smooth without binding. The fully threaded shaft made it easy to get a nut started quickly.

Ava W. ★★★★☆

The square neck on these carriage bolts really grabs the wood so you don’t need a second wrench. 316 stainless is a nice upgrade for outdoor projects where rust would be a problem. Only gripe is the threads could be a bit cleaner, but for the price they’re solid.
