Corrugated elastic washers according to DIN 137B are fasteners used to prevent bolts or screws from loosening. These washers are usually made of spring steel and can be given a surface treatment, such as mechanical galvanization or a natural color finish, 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 a preload force 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.
