    Abstract: A method for securing two pieces of sheet material is provided using a stitch preferably made by sequentially passing the grid member through two die sets. The first die set lances a strap out of the two sheets of metal such that, at the approximate center or midsection of the strap, the first layer of material is displaced completely out of the plane defined by the web, while the second layer is only partially displaced out of the plane of the web so that a portion of the second layer remains in the space vacated by the first layer of the strap. The lanced strap is then passed through a second die set, in which the first and second layers of the strap are deformed or “swaged” such that the first layer is flattened and expanded in width beyond the edges of the hole in the web created when the strap was lanced. This provides interference such that the first layer of the strap cannot pass back through the hole. Additionally, the strap in the second web is deformed and displaced into the first web to bond the two together.
