Shop Fender Washers for Wide Load Distribution
Fender washers are designed with a larger outer diameter compared to standard flat washers, making them ideal for distributing load over a wider surface area. Whether you're working with thin materials, oversized holes, or soft substrates, these washers help prevent pull-through and provide a more secure hold.
Commonly used in construction, automotive, plumbing, and DIY applications, fender washers are a go-to solution when standard washers just don’t provide enough coverage.
What Are Fender Washers Used For?
Fender washers are built for applications where extra surface area is critical. Their wide design helps improve stability and reduce damage to materials during fastening.
- Securing bolts in thin metal, plastic, or wood
- Preventing fastener pull-through in oversized holes
- Automotive body work and repairs
- HVAC, plumbing, and electrical installations
- General-purpose construction and DIY projects
How to Choose the Right Fender Washer
Selecting the correct fender washer depends on your application, environment, and load requirements. Here are a few key considerations:
- Material: Choose 304 stainless steel for general corrosion resistance, 316 stainless steel for harsh or marine environments, zinc for cost-effective indoor use, or hot dip galvanized (HDG) for durable outdoor and treated lumber applications.
- Inner Diameter: Match the washer to your bolt or screw size for proper fit.
- Outer Diameter: Larger diameters provide better load distribution and surface coverage.
- Thickness: Thicker washers offer greater strength and durability under load.
Fender Washer FAQs
What is a fender washer?
A fender washer is a flat washer with a significantly larger outer diameter compared to its inner hole. This design allows it to distribute load more evenly across a surface.
What’s the difference between a fender washer vs. flat washer?
While both are flat washers, fender washers have a much larger outside diameter, making them better suited for applications requiring increased surface contact.
When should I use a fender washer?
Use fender washers when working with thin materials, oversized holes, or when you need to prevent fasteners from pulling through the material.
Are stainless steel fender washers better?
Stainless steel fender washers are ideal for outdoor and corrosive environments due to their resistance to rust and long-lasting performance.
