Metric A4 (316) Stainless Steel Fender Flat Washer
Metric A4 (316) Stainless Steel Fender Flat Washers
When maximum corrosion resistance and surface protection are required, Metric A4 (316) Stainless Steel Fender Flat Washers provide a premium fastening solution. Designed with an oversized outside diameter, these metric fender washers distribute load over a larger surface area, reducing material stress and preventing pull-through in demanding applications.
Superior Load Distribution for Sensitive Materials
Extra-Wide Outside Diameter
The defining feature of a fender washer is its large outer diameter relative to the inner hole. This expanded footprint spreads clamping force evenly, helping to protect thin sheet metal, fiberglass, plastic, rubber, aluminum, and wood from cracking or deformation. It is an ideal choice for oversized hole reinforcement and panel stabilization.
Engineered for Metric Fastening Systems
Manufactured for compatibility with standard metric bolts, nuts, and screws, A4 stainless steel fender washers are widely used in global equipment manufacturing, marine assembly, industrial fabrication, and structural installations.
Marine-Grade 316 Stainless Steel Performance
Crafted from A4 (316) stainless steel, these washers contain molybdenum for enhanced resistance to chlorides, saltwater, and aggressive chemicals. Compared to A2 (304) stainless steel, 316 offers significantly improved protection in coastal, offshore, wastewater, and chemical processing environments.
