Embodiment Construction

[0045] The following description of the variants is merely exemplary in nature and is in no way intended to limit the scope of the invention, its application or uses.

[0046] When assembling, one of the challenges with regard to effective fastening of components involves limited access to the individual elements intended to be secured together. When the elements are positioned together such that only one-sided access to the stacked elements can be obtained, the available selection of fastening methods is greatly reduced. One such application may involve large panel components that may be positioned together with multiple overlapping edges that need to be secured. For successful connection of these components, several variants are available as in figure 1 A rivet assembly 10 with a cutting mandrel tip is shown in .

[0047] Rivet assembly 10 may include a rivet body 12 which may include a shank 14 and a head 16 . The shank 14 may be formed in a hollow cylindrical shape with...

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 102,883, filed January 13, 2015. technical field [0003] The field to which this disclosure generally relates includes fastening, and more particularly, fastening where access to a workpiece is limited to a single side. Background technique [0004] Manufactured products are often assembled from several components that are integrated into the product. Individual elements can be joined in several ways, one of which involves being fastened together. The options for fastening elements together are numerous. However, the challenges associated with joining components of assemblies are endless and there is a continuing need for new and effective devices and methods of fastening. Contents of the invention [0005] Several exemplary variations may relate to a product for a fastening element and may include a rivet body having a hollow shank with an ...
