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.
