The Flowform® screw is an innovative alternative to conventional methods of joining sheet metals together. The fastener is based on flow-drilling, a process for producing threaded or unthreaded holes in metal parts. The sharp pointed screw is spun at high RPMs. As the spinning tip comes into contact with the metal, heat is generated, making the material soft and malleable enough to be formed and perforated. The heated metal forms a deep, solid threaded bond around the screw.
