There are numerous applications that require the use of special blind rivet connections. For this purpose, GESIPA has developed several models that meet these specific requirements. Expansion blind rivets are needed when soft or porous components such as wood, hardboard, fiberglass, or drywall need to be joined with high clamping force. During the setting process, the mandrel falls out of the hollow rivet, and on the closure head side, the mandrel splits the hollow rivet into four parts. These then grip into the material. Typical areas of application include the assembly of plastic and wooden elements, caravan construction, as well as the fastening of interior linings.
