These ship cleats are made from heavy-duty, hot-dipped galvanized iron for strength & durability.  Made from the same malleable iron as our galvanized cleats, these hex head ship cleats are about 2x stronger than a standard galvanized cleat. Each cleat weighs between 4-21lbs and is fastened using (2) galvanized hex bolts (sold separately).  Contact us for questions about which bolts to use for your specific attachment needs.
