Do you need a washer that can withstand harsh environments and distributes the load effectively? The DIN 9021 marine washer in stainless steel A2 (AISI 304) is designed to provide superior corrosion resistance , especially in marine or humid environments where regular washers can quickly rust.

Thanks to its extra wide outer diameter compared to standard washers, it distributes the pressure from the screw or bolt over a larger surface area. This reduces the risk of the material underneath being deformed or damaged, especially in soft substrates such as wood or plastic.

Area of ​​application

Ideal for use in boatbuilding, docks, marine fasteners, stainless steel construction and outdoor applications where both strength and durability are required. Commonly used for attaching boat fittings, rigging parts, fittings to wood or composite , where the washer protects the surface and provides a stable, evenly distributed force transmission . The A2 stainless steel quality makes it particularly suitable for use in salty, humid or chemically aggressive environments .
