Need some serious hardware for your dock project? This heavy duty washer plate is built to last! Made from 5 gauge (that's 1/4 inch thick) hot-dipped galvanized steel, this thing won't rust out on you like cheaper options. The 9/16 inch hole punches are spaced every 3 1/2 inches, plus you get slot sizes of 9/16 x 1 5/8 inches for flexible mounting options. Specifically engineered to work with Howell and Dock Edge dock floats, so you know it's going to fit right and do the job properly. Whether you're building a new dock or repairing an existing one, this washer plate provides that solid foundation you need to keep everything secure. The galvanized coating means it can handle being in water without corroding - super important for marine applications. Installation is straightforward if you've got the right tools and some basic DIY skills. Much better quality than what you'd find at big box stores, and definitely worth the investment if you want your dock to last through seasons of use. Perfect for boat docks, fishing piers, or any waterfront structure that needs reliable, heavy-duty hardware. This is one of those 'buy it right or buy it twice' situations - and this washer plate is definitely the right choice!
