Applications

RS PRO washers are an essential part of any fastener assembly. They decrease the surface load when joining materials, meaning there is less pressure on the material, resulting in a decrease chance of wear and tear over time. You can use them to make maintenance easier by allowing for smoother loosening and tightening of components. Plain washers are commonly used in many electronic, food, chemical and construction applications.

What is a Form A Washer?

Form A is a British Standard indicator for the metric outer diameter and thickness of a steel washer. It is a quick reference that in this case indicates a type of washer with a 'normal' diameter and thickness. Form A washers are suitable for most applications.

What is the difference between a plain washer and a penny washer?

Other than standard washers, you might also hear washers referred to as fender washers, penny washers and mudguard washers. These 'repair washers' have a larger external diameter in comparison to the inner diameter, meaning a larger distribution of surface area. They can be used with a worn fixing hole or to fasten larger surface areas.
