Failure to adhere to the grip range may also cause a premature break or difficulty in clearing the spent mandrel from the setting tool.Īlso be sure to account for the theoretical grip versus the actual grip. Rivets set under-grip can bend and offset, reducing the overall strength and aesthetic appearance. Rivets set over-grip will not retain the mandrel head, causing it to fall out of the rivet body after setting. Setting rivets outside of their specified grip range can lead to functional failures. This thickness is commonly called the grip range.
All manufacturers list a range of material thickness in which the product will perform properly. If the rivet is applied over or under its intended grip range, it may not work properly.
