DIN 7349 Heavy Duty Flat Washers are specially designed flat washers for use with heavy duty clamping sleeve bolts, especially where a large load bearing surface is required. These washers are typically thicker and have a larger outside diameter than standard flat washers to provide a larger support area and better load distribution.
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:
Enhanced load carrying capacity: Due to the thickened design of the washers, they are able to withstand higher preloads and working loads for heavy machinery and structural connections. Corrosion resistance: Galvanization and other surface treatments provide additional protection against corrosion, making the washers suitable for use outdoors or in wet environments. Hardness: A hardness rating of 200 HV ensures the durability and stability of the washers under high loads. COMPATIBILITY: Designed for use with DIN 1481 standard heavy duty clamping sleeve bolts, ensuring good compatibility and reliability of the connection.
Scope of Application
Building and civil engineering: In building and civil engineering, DIN 7349 washers are used to connect beams, columns and other structural components, especially where high strength and adjustability are required. Machine and plant construction: In machine and plant construction, they are used to fix and adjust machine components such as bearings, gears and motors. 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. Bridges and pylons: In the construction of bridges and pylons, DIN 7349 washers are used to ensure the stability and safety of the structure. Marine engineering: Due to their corrosion resistance, these washers are also suitable for structural connections in marine engineering and offshore platforms.
