Marine Fasteners Fender Washer Stainless Steel

Marine Fasteners stainless steel fender washers, also called large-OD flat washers or oversized washers, have a much larger outside diameter than a standard flat washer of the same bolt size. The wider face spreads clamping load over a bigger area. This helps prevent pull-through and reduces point-load stress on thin or soft materials.

Key Features:

• Stainless steel construction resists corrosion in marine, outdoor and other damp environments
• Oversized outside diameter spreads hardware loads and bridges oversized or worn holes
• Suited to through-bolting where no backing plate is used
• Helps protect fiberglass, wood, plywood, plastics and thin sheet metal from crushing or dishing
• Multiple sizes are offered to match common fastener diameters

These washers suit boat hardware, panels, brackets, docks, trailers and general repair work. Choose the size that matches your fastener and application from the available options.
