  • Method for establishing a nail connection between two non-prepunched components
    Patent number: 8375549
    Abstract: A method is described for establishing a nail connection between two components as well as a nail therefor. The nail is driven through the non-prepunched components in the joining area at a high speed such that the nail tip fully penetrates both components and forms a toric-shaped material bulge in the nail-head-side component, which protrudes into a circular groove of the nail head, and a crater-shaped material bulge is formed in the component facing away from the nail head, which protrudes in the opposite direction.
