RS PRO Bright Zinc Plated Steel Mudguard Washers, M5

From the trusted RS PRO Brand, these zinc plated mild steel mudguard washers are generally used with a machine threaded fastener and nut to spread the load over a greater surface area when tightening a bolt, screw or nut. Their larger diameter means they are more suitable for use with worn thread holes than standard washers. As they are bright zinc plated they have an element of corrosion resistance and are suitable for use in many environments. They are supplied in bags of 100.

• Zinc plated mild steel

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 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.
