18-8 Stainless Steel Fender Washers are round thin flat washers with a larger outside diameter than standard flat washers of the same bolt size. They are used when a large washer diameter is needed to increase surface area and prevent fastener pull-through. 18-8 Stainless Steel (300 Series) offers effective resistance to corrosion in damp environments and exterior applications.
They are also available in Type 316 Stainless Steel for superior corrosion protection in Marine, Industrial and more severe exterior applications.
