Movies and TV shows consistently promote lead characters who are able to complete their mission with little or no help from others. In the world of fastening, self-tapping screws fit this role better than any fastener, as they have the ability to create mating threads in metallic and nonmetallic base materials. By eliminating the tapping process, these fasteners (thread-cutting, thread-rolling and thread-forming screws) help manufacturers save money and increase production.
Nidec America Corp., one of the world’s largest electric motor manufacturers, has benefitted from self-tapping and self-drilling fasteners for more than a decade. Earlier this century, Nidec engineers were faced with a challenge related to an assembly that involved joining an aluminum heat sink (stamped or extruded) to a thermal transfer pad with a proprietary rivet available from only one supplier worldwide.
