DIN 125 washers are standard flat washers with a uniform thickness, while DIN 127 washers are split or helical spring washers with a slightly curved profile.
Both types of washers are made from carbon steel and coated with zinc plating to enhance corrosion resistance and durability.
Flat washers (DIN 125) serve several functions, including:
Providing a smooth bearing surface under the head of a bolt or nut to prevent damage to the mating surface.
Distributing the load of the fastener over a wider area to reduce the risk of deformation or damage to the substrate.
Spring washers (DIN 127) provide additional locking and preload retention capabilities by exerting spring force between the fastener and the substrate. This helps prevent loosening due to vibration or thermal expansion.
