Self piercing rivet or also known as SPR is a type of rivet that is used to join aluminium panels that does not require a hole to be drilled before hand. SPR is forcefully pressed together on panels to make a join that can hold vertical force exerted to separate the panel. SPR can be applied on panel using a minimum 8 tonne hydraulic press with dedicated die kit. This is a joining method that is used by many OEMs
