FASTENING DEVICES, ASSEMBLIES AND RELATED METHODS

摘要

Fastening devices are disclosed herein with variations on how said devices resist loosening or un-fastening from a structure or structures. In some examples, the fastening devices accomplish the removal resistant condition by using a spring component engaging ridged surfaces. The spring component generally consists of a spring ring conveniently coiled to a canting position. One exemplary design is characterized by incorporating a screw element with its head underside surface being ridged and a lock element with a ridged topside surface and engaging the two ridges surfaces. Another exemplary design is characterized by a screw element having a head outer sidewall being ridged for cooperating with a bore having a ridged inner sidewall. The bore can be part of a first body or structure or a lock element.
