18-8 Stainless Steel Fender Washers
What are 18-8 stainless fender washers? 18-8 stainless steel fender washers are oversized flat washers that spread a fastener's load across thin or soft material, made from corrosion-resistant 18-8 stainless. The wide diameter resists pull-through, while the stainless grade resists rust in wet and outdoor use.

Why use 18-8 stainless fender washers?
An 18-8 stainless fender washer combines an oversized outer diameter, which stops nuts and bolt heads from pulling through thin sheet metal, wood, and plastic, with the corrosion resistance of 300-series stainless for outdoor and freshwater use. It is the everyday stainless fender washer for general work. Pair it with 18-8 or 304 stainless bolts and nuts so the whole joint shares the same corrosion resistance. For coastal or saltwater exposure, step up to 316 or metric A4.
Why choose 18-8 stainless fender washers
- Wide bearing: oversized diameter resists pull-through in thin material.
- Corrosion resistant: 18-8 stainless resists rust in wet and outdoor use.
- Non-staining: will not rust-streak the mounting surface.
- Versatile: works on metal, wood, plastic, and slotted holes.

18-8 Stainless Fender Washers FAQ
Is 18-8 the same as 304 stainless?
18-8 falls within the family that includes 304, with about 18% chromium and 8% nickel. The terms are often used interchangeably for washers.
Is 18-8 good for coastal use?
18-8 handles most outdoor and freshwater exposure but can pit in salt. For coastal or saltwater use, choose 316 or metric A4.
Why use a fender washer instead of a flat washer?
The oversized diameter spreads load over a much wider area, which resists pull-through in thin sheet metal, wood, and plastic.
