ADDITIONAL FLANGE SIZE: Adding these to your rivets will increase the flange allowing for more clamping force distributed over a larger surface area. Extremely useful in applications working with thin metals to prevent pull through.
HIGH QUALITY Aluminum : Persberg Rivet washers are 100% aluminum, giving them one of the highest forms of corrosion resistance. This makes them the perfect choice for use in any environment (including marine/saltwater).
