Square, Fender & Hex Washers: Versatile Solutions for Marine Hardware

Marine hardware comes in all shapes and surfaces. Square washers and fender washers are ideal when dealing with large surface areas or when load-bearing is more distributed—like in fiberglass hull panels or wood-to-metal structural mounts. Hex washers, used with hex bolts, improve torque flatness and distribute load while presenting a clean finish. 

By sourcing from experienced manufacturers, you gain access to certified material sheets, reliable surface finishes (e.g., passivated SS316), and options such as serrated hex washers. These washers not only reinforce assemblies—they help maintain structural fairness, load distribution, and corrosion protection across various substrates. Whether installing hardware on fiberglass, wood, metal, or composite materials, trusting a marine specialist ensures that every washer contributes to long-term structural performance.
