An overview of flat washers
Washers
Washers distribute forces over a larger area. This reduces the pressure exerted on the contact surfaces of a joint. At the same time, it also protects the component surface, as the relative movement between the fastener and the component only takes place in the joint between the washer and the fastener.
Standards
- DIN 125 A similar to ISO 7089/7090
- DIN 125 B similar to ISO 7089/7090
- DIN 126 similar to ISO 7091
- DIN 1052
- DIN 1440 similar to ISO 8738
- DIN 1441
- DIN 432
- DIN 433 similar to ISO 7092

- DIN 9021 similar to ISO 7093
Working principle
Distributing the pre-tensioning force over a larger area reduces the pressure exerted on the contact surfaces of the joint. This reduces deformation and creep phenomena. Washers protect sensitive surfaces from mechanical damage.
Material
In addition to steel in different hardness classes, available materials include stainless steel, plastic, aluminium and brass. Care must be taken to use washers of the appropriate hardness, particularly when using high-strength screws.
Surfaces
Our products can be coated with different surface finishes, depending on requirements and application. We will be pleased to give you individual advice on the right coating system.
We offer the following surfaces as standard:
- Plain
- Zinc plated (industry standard)
- VZD (zinc plated with thick layer passivation)
- ISO Standard Galvanized
- Zinc-nickel
- Zinc flake
