- Typically used in soft metals or oversized holes
- Create a larger diameter of pressure during fastener installation
- The larger diameter helps to spread our pressure over the material preventing pull through
Rivet Backup Washers are for use with Pop (Blind) Rivets, particularly in soft metals. Rivet Backup Washers create a larger installed diameter which creates a larger surface area and prevents pull through by distributing force over a larger area than a standard blind rivet.
