Penny Washers

Penny washers are washers with a big diameter that are used to distribute the weight and alleviate the stress placed on materials with a thin gauge or that are soft, such as lumber. Because they are able to spread the pressure, they prevent the surface from being harmed while the product is being installed.

They come in a range of sizes, with outer diameters ranging anywhere from 20mm to 50mm, and can be zinc plated or made of stainless steel. Penny washers, also known as mudguard washers and repair washers, are another name for these kinds of washers.

What Are Washers Used For?

A washer is a plate or disc that has holes punched in it and may be constructed from a wide range of materials. It is used to reduce the amount of rotative friction that occurs between two surfaces. For instance, between a threaded fastening, such a bolt or a screw, and the surface into which the fastening is bolted or screwed. Another example would be between a nut and a bolt. The employment of metal disc washers, such as penny washers, which are popular in a wide number of applications is something that all of us are familiar with.

Penny washers, also known as flat washers, are the most frequent type that you are likely to come across and are typically eligible for three different purposes:

Handling Pressure: The application of pressure from the nuts and bolts in such a way that it is distributed equally throughout the component to be secured, hence lowering the likelihood that the component would be damaged.

Offering Surface Area: The providing of a smooth, level site for the nut or bolt to bear onto, hence lowering the probability of the fastening coming free as a result of uneven fastening surfaces.

Provides a Barrier: The formation of a watertight barrier to prevent the entry of water into a space (these are then known as plumbing washers)

How Are Penny Washers Used?

Penny Washers are made of both stainless steel and plastic and may be utilised in a wide variety of industries, with specialist stock available upon request. See below to review some of the ways penny washers are used:

Architectural Art: As any architectural artist will tell you, having the right equipment for your craft is essential to creating strong and well made pieces of architectural art.

Stainless Steel Sculptures: No matter what your steel sculptures are intended for, penny washers are a great choice as they are highly durable and strong enough to keep pieces together.

Architectural Metalwork: Not only do penny washers provide support for larger applications, but they are designed to withstand all the Great British weather has to throw at them, making architectural metalwork long lasting.

Marine Applications: Due to their waterproofing capabilities making them resistant to corrosion, penny washers are great in marine applications, for both repairs and initial builds of marine tools and equipment.

Model Making: With many sizes available, these washers are a good choice for model making, whether that’s for hobby modelling or professional modelling.

Finding the Correct Thread Size

Whether you’re ordering a one off supply of washers, or you’re looking for a bulk-pack for your current and future projects, it’s important to make sure that you are choosing the correct thread size for application to ensure they’re appropriate for screws and project load.

The good news is that dimensions for flat washers should be nearly the same regardless of where you buy them or who produces them. This is due to the fact that all manufacturers of metric flat washers adhere to a standard set of dimensions defined by a set of Forms.

If you need help picking the correct Form for your needs, our team is here to provide assistance!

Frequently Asked Questions

What is a penny washer?

A penny washer, also known as a fender washer, is a flat, circular metal washer with a central hole. It typically has a larger outer diameter compared to a regular washer, resembling the size of an old British penny coin, hence the name. Penny washers are commonly used to distribute the load of a threaded fastener, such as a bolt or screw, over a wider surface area.

What are penny washers used for?

Penny washers have various applications in construction, woodworking, automotive, and other industries. They are often used to provide extra stability and prevent damage when fastening materials together. They can be used to reinforce connections, reduce the risk of pull-through or surface damage, and improve the overall strength and longevity of an assembly.

What are the different materials available for penny washers?

Penny washers are typically manufactured from different materials, including steel, stainless steel, brass, and zinc-plated steel. The choice of material depends on the specific requirements of the application. For example, stainless steel penny washers are commonly used in outdoor or corrosive environments due to their resistance to rust and corrosion.

How do I choose the right size of penny washer?

When selecting a penny washer, it is important to consider the diameter of the bolt or screw you are using. The washer should have an inner diameter large enough to accommodate the fastener without interfering with its threads. Additionally, you may want to consider the outer diameter of the washer to ensure it provides adequate support and load distribution for your particular application.

Can penny washers be reused?

In general, penny washers can be reused as long as they are still in good condition. However, it is essential to inspect them for any signs of wear, deformation, or damage before reuse. If a penny washer shows signs of being compromised, it could loosen if reused and so it is recommended to replace it with a new one to ensure optimal performance and safety in your fastening application.
