Abstract
A method of inserting a rivet having at least a body portion and a mandrel having means for cutting and peeling back the rivet into portions which curl back on the rivet body into a solid substance. The rivet and mandrel are inserted into the solid substance without completely piercing through the solid substance. The rivet is then cut and peeled back into portions which curl back on the rivet body within the solid substance. The invention is also directed to a product comprising a solid substance, and a material fastened to the solid substance by at least one rivet which extends through the at least one material and into the substance without completely piercing through the substance. The at least one rivet has been cut back into portions which curl back on the rivet body, thereby attaching the material to the solid substance.
