The GB7244/DIN127B standard refers to Heavy-duty spring washers, which are fasteners used to prevent nuts or bolts from loosening. These washers usually have one or more wavy edges to provide additional friction and thus increase the stability of the connection.
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:
PREVENT LOOSENING: Heavy-duty spring washers are designed to prevent nuts or bolts from loosening due to vibration or shock. HIGH LOAD-BEARING CAPACITY: Due to their heavy-duty design, these washers are able to withstand high preloads and are suitable for high load applications. Multiple Materials: They can be made of different materials such as carbon steel and stainless steel to suit different corrosion resistance and strength requirements. Surface treatment: The surface of the washers may be zinc-plated, mechanically galvanized, or other surface treatments to improve corrosion and abrasion resistance.
Scope of Application
Heavy Machinery: In heavy machinery and equipment, for fixing and adjusting machine parts such as bearings, gears and motors. Building Structures: In building and civil engineering, for connecting beams, columns and other structural components to provide stable and reliable connections. Bridges and pylons: In the construction of bridges and pylons, for ensuring the stability and safety of the structure. Chemical industry: in the construction of chemical plants, these washers are used to connect and secure equipment such as pipes, pressure vessels and heat exchangers due to their good corrosion resistance.
