Metric A4 (316) Stainless Steel Fender Flat Washer
Metric A4 (316) Stainless Steel Fender Flat Washer: Maximum Surface Protection in Harsh Environments
The Metric A4 (316) Stainless Steel Fender Flat Washer is engineered for superior performance in corrosive and marine environments. With its extra-wide outside diameter, this washer offers enhanced load distribution, making it ideal for applications where protecting soft or thin materials is critical.
Made from A4 (316) stainless steel, this fender washer provides exceptional resistance to rust, saltwater, chemicals, and extreme weather. The addition of molybdenum in 316 stainless makes it the preferred choice over standard 304 stainless (A2) for coastal, industrial, and chemical processing environments, where long-term durability is essential.
Fender washers are commonly used to reinforce oversized holes, spread load across larger surfaces, and prevent fasteners from pulling through soft materials like plastic, rubber, fiberglass, aluminum, and wood. The metric sizing ensures compatibility with standard metric bolts, nuts, and screws used in global manufacturing, marine, construction, and equipment assembly.
Whether you're building marine structures, assembling corrosion-sensitive equipment, or reinforcing panels, the Metric A4 fender washer delivers unmatched strength and stability.
