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 440 R similar to ISO 7094
DIN 440 V similar to ISO 7094
DIN 463
DIN 6340
DIN 7349
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
