Setup, Compatibility & Care
For optimal results, ensure the washer is placed on the bolt shank before threading the nut or inserting the bolt into the tapped hole. These washers are specifically sized for M20 hardware; ensure the inner diameter of the washer fits snugly against the M20 bolt. To maintain the life of the connection, check for signs of rust after long periods of outdoor exposure, although the zinc plating is designed to mitigate this. Avoid reusing spring washers if they have been flattened to the point of permanent deformation, as their ability to provide spring force will be significantly reduced.
