Conical spring washers feature a unique disc spring design that delivers high spring efficiency, achieving 70-90% of the contact pressure of Grade 8.8-10.9 bolts. These washers are engineered to compensate for subsidence in screw connections and prevent loosening through purely frictional locking, ensuring long-term reliability in demanding environments.
Technical advantages include high spring efficiency, effective settlement compensation for joint relaxation and thermal expansion, friction-based locking compliant with DIN 6796, and a low-profile design that saves up to 40% height compared to coil spring alternatives. These features make conical spring washers ideal for critical applications such as pressure vessels, structural steelwork, and power transmission systems.
Available in a range of materials including 65Mn steel, 316 stainless steel, 304 stainless steel, and carbon steel (Q235), these washers cater to diverse industrial needs. Surface treatment options include Dacromet, galvanizing, black oxide, zinc-chromate coating, nickel plating, and phosphating, each offering specific benefits for corrosion resistance and durability in various environments.




These washers are suitable for use between nuts and bolts in applications requiring precise preload control and vibration resistance. Customization is available for non-standard parts based on customer drawings, with options for various sizes, materials, and surface treatments to meet specific requirements.
