DIN127B standard deals with light spring washers (Light spring washer), which are single-turn elastic washers usually used on bolts or screws to provide extra clamping force and prevent loosening. These washers deform elastically when under pressure, creating a spring-like force that helps maintain preload and prevents the joint from loosening due to vibration.

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:

Elastic design: The elastic design of light spring washers allows them to deform elastically when subjected to external forces, thus providing an elastic force that maintains a tight connection between components. Prevent loosening: These washers are effective in preventing nuts or bolts from loosening due to vibration or shock, maintaining the stability of the connection. Material diversity: usually made of carbon steel or alloy steel, such as 65Mn material, the surface can be oxidized to improve corrosion resistance. Economical and practical: Compared with other types of washers, light spring washers are less costly and suitable for large-scale applications.

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 connecting 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 fixing, to prevent loosening of components due to vibrations during driving. Electronic and electrical equipment: In electronic and electrical equipment, they are used to ensure the stability of the connection and to prevent loosening of the connection parts due to vibrations generated during the operation of the equipment.
