The DIN137B standard deals with wave spring washers, which are washers with a corrugated shape used to provide preload and prevent bolts or screws from loosening. These washers are typically made of carbon or stainless steel and may have a surface treatment, such as zinc plating or blackening, to improve corrosion resistance and aesthetics.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Corrugated design: The corrugated design of the corrugated elastic washers enables them to provide elastic deformation during installation, which generates preload and effectively prevents loosening of the connecting parts. High elasticity: These washers have good elasticity, which can absorb vibration and shock to a certain extent and protect the connecting parts from damage. Corrosion resistance: Surface treatments such as zinc plating can improve the corrosion resistance of the washers, making them suitable for a variety of environmental conditions.

Scope of Application

Machinery and equipment manufacturing: In machinery and equipment manufacturing, for fixing and adjusting machine parts such as bearings, gears and motors. Building and civil engineering: in building and civil engineering, for joining beams, columns and other structural components to provide stable and reliable connections. Automotive industry: In automotive manufacturing, for connecting automotive components such as chassis and body fixings.
