Fender washers (also known as penny washers) are flat washers with a larger outer diameter in relation to their inner hole. This allows them to distribute the force of a screw or bolt to prevent pull-though and can be useful in applications where thin materials need support.
They also prevent corrosion, reduce abrasion and noise and provide insulation. However, they add extra thickness to a project and can be more expensive than other washers.
Larger Outer Diameter
Fender washers are flat washers that have a much larger outer diameter in proportion to their center holes than standard flat washers. The oversized outer design allows them to be placed under the head of a bolt or nut and helps to distribute the forces applied when tightening. The large outer diameter also means that fender washers offer more protection against damage by spreading the load over a greater area than other types of washers.
Fender Washers are commonly used in auto-body restoration and other sheet metal work as well as plumbing, electrical and wood projects. They are also commonly used with corroded or rusted parts to help hold fasteners in place while they are being removed or reinstalled.
These washers are available in a variety of materials including stainless steel, neoprene and zinc for extra strength and durability. They can be found in a range of sizes and are available with or without a hole to accommodate different bolt or screw diameters.
Better Distribution of Loads
The oversized outer diameter on fender washers helps distribute forces caused by tightening a bolt or nut more evenly. This design makes them better for use with thin or soft materials like sheet metal, and it also helps prevent pull-through of the fastener.
These washers are often used in automotive, plumbing and electrical applications where a larger distribution of load is required. They are also often used to correct alignment issues in machinery.
The large outer diameter on these washers also offers more stability than regular flat washers, so they are better for use in corroded or rusted parts. They can help secure a nut in a rusty or corroded hole and prevent it from coming loose over time. These washers are also used to protect surfaces, such as preventing corrosion between an aluminum surface and a steel screw. They can also reduce noise, vibration and abrasion in mechanical projects. These washers can be purchased in a variety of sizes and materials, including stainless steel and low carbon steel.
Better Protection Against Damage
When you’re working on an automotive project, installing plumbing or performing electrical work, washers protect delicate materials from damage. These small, flat fasteners provide insulation and help distribute the pressure of a nut or bolt over a larger surface area to reduce the risk of the material being dented or cracked.
Washers are also useful for absorbing vibrations. They can be made from a variety of materials, including rubber or plastic, and are often used to seal threaded connections against water or other liquids. This can prevent leaks and other forms of contamination.
Fender washers are different from standard flat washers in that their outside diameter is much larger in proportion to their center hole. This helps to spread the load on thin or soft materials, and it allows you to make a connection to an oversized hole. In addition to this, fender washers are typically more durable than other types of washers. This makes them appropriate for a wide range of applications, including marine projects.
Can Be Used With Rusted or Corroded Parts
Washers are used to protect mechanical parts from damage when they’re inserted into other materials. They work by distributing the load of the threaded fastener, which would otherwise pull or wear down the material it’s in contact with.
Fender washers offer additional advantages because they have a large outer diameter, which makes it easier to distribute the fastener’s load over a broader area. This allows them to be used in contact with corroded or rusted parts without damaging the part.
You can find fender washers in different metals, finishes and sizes depending on your needs. For example, if you’re working in an environment with harsh chemicals, you should look for options like Hastelloy and Monel, which are resistant to chemical attacks.
You can also find fender washers in materials like stainless steel and low carbon steel for added strength and durability. They’re ideal for auto-body restoration and other sheet metal projects, as well as for plumbing and electrical work.
