Rivet Backup Washers

Blind rivet backup washers are used with blind rivets to provide additional support for fastening applications involving softer materials. POP rivet backup washers are also useful for surfaces that require a larger installed surface diameter, when working with holes that have an irregular shape, or to provide additional support.
 
Blind rivet backup washers are used by sliding the washer over the blind rivet so it rests against the flange, then inserting the blind rivet into a pre-drilled hole in the material and using a rivet tool to deform the rivet and create a permanent hold. For applications where a thin or delicate material could tear, pop rivet backup washers can also be used to secure the back side of a material, if it is accessible. Simply slide the rivet into the hole in the material, then slip the backup rivet washer onto the end of protruding portion of the rivet head. If necessary, hold the washer in place while you deform the blind rivet.

Steel and Aluminum Blind Rivet Backup Washers

 
POP rivet backup washers should be chosen in the same material as the blind rivet and with similar properties to the material being used for your fastening application.  Aluminum provides less tensile strength than steel but is a lightweight and corrosion-resistant solution that is suitable for many applications. Steel provides higher tensile strength but should not be used in applications where rust and corrosion are a concern.
 
When selecting your blind rivet backup washers, the ID should also closely match the diameter of your rivet to create a secure fit. Our pop rivet backup washers are offered in aluminum and steel with four different size options and can be used with any standard blind rivets.
