Marine Fasteners Fender Washer Stainless Steel

These stainless steel fender washers (also called oversized or large-diameter flat washers) are made for marine and boating hardware. Each has a large outer diameter compared with its inner hole. This spreads clamping load over a wider area on fiberglass, wood, aluminum and thin sheet material.

Key Features:

• Stainless steel construction for corrosion resistance in wet, salty and humid environments
• Wide outer diameter relative to the hole size helps prevent pull-through on thin or soft materials
• Flat, smooth profile for even contact with the mounting surface
• Works with bolts, machine screws and threaded fasteners to back up cleats, hatches, rails, brackets and other deck and hull hardware
• Available in multiple sizes and pack quantities to suit different projects

Use fender washers where a standard washer would sink into the material or leave too little bearing surface. They suit boat repair and maintenance, trailer hardware, RV, powersports and general utility mounting. Choose the size that matches your fastener.
