Metric Stainless A4 (316) Fender Washer, DIN 9021B
Our Metric Stainless Steel A4 (316) Fender Washers manufactured to DIN 9021B are corrosion‑resistant load‑distribution components designed for applications requiring an oversized outer diameter. Made from A4 stainless steel (Type 316), these washers provide superior resistance to corrosion, chlorides, saltwater, and harsh environmental exposure, making them ideal for marine, chemical, and outdoor applications.
The DIN 9021B fender washer design features a significantly larger outside diameter relative to the center hole, allowing clamping force to be spread over a wider surface area. This helps reduce pull‑through, protect thin or soft materials, and improve joint stability in bolted assemblies exposed to vibration or environmental stress.
Engineered for durability and performance, A4 Stainless DIN 9021B Fender Washers are commonly used in marine hardware, construction, sheet‑metal assemblies, equipment enclosures, structural components, and industrial installations where additional bearing surface is required. The fender style is especially effective for slotted holes, thin materials, and uneven mounting surfaces. Stainless 316 construction ensures long service life in corrosive and moisture‑exposed environments, while DIN compliance ensures consistent dimensions and reliable fit across metric fastening systems. Available in a wide range of metric sizes, these washers provide a dependable solution for OEM production, maintenance, and repair operations.
