RS PRO Lock Washers - BZP Steel


From the reliable RS PRO brand, this external tooth lock washer provides superior security for fixings and fastenings. Like standard washers, it distributes the load of a bolt against a surface material. However, its unique locking action prevents the fastener from turning, reducing the likelihood of the fixing loosening over time or under repeated stress. This makes it particularly useful in applications where vibration is a concern.

Features and Benefits


  • Used with threaded fasteners (for example, a bolt or a nut)

  • Used to prevent the fastener from loosening, caused by vibration

  • External teeth effectively ’bite’ into the fastener and substrate surfaces as the fastener is tightened

  • Made from Steel

  • The bright zinc plated (BZP) finish offers resistance against corrosion

  • Conforms to DIN 6797A specifications

    • Applications


  • Domestic appliances such as washers and dryers

  • Industrial machinery

  • Automotive industries
