Rotation restraining self-piercing rivet |
摘要 |
The present invention is a self-piercing rivet wherein the hollow shell has an external axial asymmetry wherein the asymmetry is with respect to the axis of rotation of the hollow shell. Once installed in a stack of sheets, the asymmetric self-piercing rivet prevents relative sheet rotation of the sheets relative to the axis because of rotational interference caused by the external axial asymmetry of the hollow shell.
