Galvanised Steel Plain Washers, 5/16in

Introducing the range of RS PRO Flat Washers, a high-quality fastener solution for providing a secure hold for a nut or bolt, or as a spacer in a wide range of applications. Each fastener is made from steel with either a zinc or galvanised finish, making them much more cost-effective than their stainless-steel counterparts, while still offering a high level of protection against surface rust and oxidisation.

Washers are designed specifically for ease of use and simplicity. They are used for applications where a nut or bolt needs to be tightened to prevent the fastener from loosening or to distribute the load evenly from the nut or bolt head over a larger area. Additionally, they can also serve as a spacer through the fastener before driving it into the surface or object, which in turn creates an additional surface which prevents the fastener from going too deep. Washers are most commonly used in:

• Household applications and DIY


• Electronics and industrial manufacturing


• Construction and building
