Key features of the Stainless Steel DIN 7980 Washer include:


  • Material: Stainless steel is known for its durability and resistance to corrosion, making it an excellent choice for applications where the washer may come into contact with water, chemicals, or other corrosive substances. This ensures the longevity of the washer and prevents it from deteriorating over time.
  • Design: DIN 7980 washers are characterized by their unique design, which includes an internal and external diameter that is slightly oval or elliptical. This design allows for a secure fit and prevents the washer from turning or rotating when fastened.
  • Applications: These washers are commonly used in conjunction with various fasteners, such as bolts or screws, to distribute the load and prevent damage to the surface being fastened. They are often used in structural applications, machinery, and equipment assembly.
  • Locking Feature: The elliptical shape of the DIN 7980 washer provides a degree of locking action, which means that it helps to prevent nuts or bolts from loosening due to vibration or other external forces. This feature is particularly important in applications where safety and stability are critical.
  • Standardization: The DIN 7980 washer is manufactured in accordance with the Deutsches Institut für Normung (DIN) standards, which ensures consistency in its dimensions and performance. This standardization makes it easy for engineers and manufacturers to specify and use these washers with confidence.
