The saddle elastic washer is a specialized gasket engineered to enhance the reliability of mechanical fastenings by providing anti-loosening properties and increased friction. Its unique saddle shape ensures that after a bolt or screw is tightened, it generates additional frictional force, effectively preventing loosening due to vibrations or external forces. This makes it an essential component in environments where stability and safety are critical.
Applications span across various industries, including heavy industry, general manufacturing, and the automotive sector. It is particularly beneficial in dynamic or high-vibration settings, such as machinery assembly, where maintaining bolt integrity is paramount. The washer functions as a curved wave spring type, offering consistent performance under stress.
Manufactured from high-grade carbon steel, the washer undergoes precise surface treatments such as nickel plating, zinc plating, or Dacromet coating to enhance corrosion resistance and durability. Production adheres to international standards including DIN137A and GB860, ensuring compatibility and reliability in metric system measurements. Specifications range from M2 to M10, catering to diverse fastener sizes.
Packaging options include plastic bags, cartons, and pallets for secure transportation and storage. As a product intended for industrial and research use, it is supplied in bulk quantities with a minimum order quantity of 10,000 pieces, supporting customization for non-standard requirements. The production capacity allows for large-scale orders, making it suitable for wholesale and OEM partnerships.
