Common Uses for Fender Washers
You’ll see fender washers used anywhere the fastener needs extra bearing surface. If you work in automotive, you'll see fender washers used on body panels, brackets, and light mounts. They’re also common in woodworking, fence builds, and general repair work when the hole is slightly oversized or the material is soft. The larger outer diameter helps prevent pull-through and reduces surface damage. Contractors use fender washers on framing connectors, strapping, and utility mounts. When selecting a washer, check inner diameter for proper fit and make sure the outside diameter gives you the coverage you need. Extra-thick options can also help when you want less bending and a more solid clamp, especially on thin sheet metal or plastic where standard washers can sink in over time.
Benefits of Using Fender Washers in Assembly & Repair
The main benefit is load distribution. Fender washers spread clamping force across a larger surface than a standard flat washer, which helps protect the parent material and keeps fasteners from sinking in. That matters with sheet metal, plastics, and wood where the surface can crush or crack. They’re also useful when the bolt hole isn’t perfectly sized or has worn over time, since the wide outside diameter can bridge and stabilize the connection. Material choice helps too. Low-carbon steel works well for general indoor applications, while stainless steel is a better fit for moisture, chemicals, or outdoor exposure. For coated steel, zinc-plated washers offer basic protection against rust in many everyday environments. Choosing the right diameter and thickness can reduce rework and help the joint stay tight longer.
Bulk Fender Washers for Manufacturing & Contractors
If you’re ordering for a shop, a line, or a jobsite, bulk fender washers keep installs consistent and reduce downtime from missing hardware. Many buyers standardize on a few common bolt sizes and stock matching washers by inside diameter and outside diameter so crews don’t have to guess. Buying fender washers in bulk can also help keep the per-unit price lower, especially when you’re using them daily in production or field service. Fastener SuperStore carries multiple finishes and materials so you can match the job, whether you need coated steel for general builds or stainless for exposure concerns. If you’re comparing fender washers for sale, check availability, packaging quantities, and shipping details, including that shipping costs are non-refundable. Bulk fender washers are a simple way to keep bins full and build moving.
Frequently Asked Questions:
What are fender washers?
Fender washers are wide-diameter washers designed to spread load over a larger area than a standard washer. They’re a flat washer style with a larger outside diameter and a smaller hole sized for the fastener, helping reduce pull-through and surface damage on softer materials.
Why choose fender washers over standard washers?
Choose fender washers when you need more coverage around the hole. Their larger outer diameter spreads clamping force, which helps prevent the fastener from pulling through thin material or crushing softer surfaces. They’re also handy when holes are oversized or slightly irregular.
What materials do fender washers come in?
Fender washers are available in steel and stainless steel options, with finishes that match the environment. Common choices include zinc-plated steel for general protection, black oxide for indoor use, and galvanized finishes for tougher exposure. Stainless options include 18-8 and 316 for corrosion resistance.
Can fender washers be used with wood, metal, or plastic?
Yes. Fender washers work well with wood, metal, and many plastics because they spread the load across a wider area. Just match the inside diameter to the bolt size and choose a thickness and outside diameter that supports the material without bending or cracking.
What industries commonly use fender washers?
Fender washers are widely used in various industries, such as the automotive industry, sheet metal fabrication, construction, maintenance, HVAC, and general manufacturing. Anywhere a connection needs extra bearing surface or protection around a hole, fender washers are a common, practical hardware choice.
