Metric 18-8 Stainless Steel Fender Washers (A2)
What are metric 18-8 stainless fender washers? Metric 18-8 stainless fender washers, grade A2, are oversized metric flat washers that spread a fastener's load across thin or soft material. Made from corrosion-resistant 18-8 stainless, comparable to metric A2, the wide diameter resists pull-through while the stainless grade resists rust.
How do I size metric fender washers?
Metric fender washers pair a wide outer diameter, which stops nuts and bolt heads from pulling through thin material, with metric sizing for M-series bolts. In 18-8 stainless, comparable to metric A2, they offer strong corrosion resistance for general outdoor and freshwater use. Match the washer to your metric bolt size, and pair it with A2 metric bolts and nuts to keep the joint at one corrosion grade. For coastal or saltwater exposure, step up to A4 metric, comparable to 316.
