Most mechanical joints, both sealed and not sealed use either threaded fasteners such as conventional nuts, bolts and set screws or non-threaded fasteners such as conventional spring pins. Safety, economy, reliability and environmentability of structures, piping systems, both portable and fixed, their combination, mechanical equipment, power plants, jet liners, ships, etc., rely on the predictable performance of involved fasteners. Due to the variety of factors, a predictable performance of corresponding commercial fasteners is not always fully attainable. Such uncontrollable conditions as in-service thermal cycling, vibration, metal flattening, metal fatigue, human error, possible malpractice, tampering with or neglect, occuring during installation, operation or maintenance, make performance prediction difficult and increase associated costs. This invention comprises a number of value-added improvements of commercial fasteners which may significantly increase the accuracy of prediction in safety, economy, reliability and environmentability of involved systems if proposed improved fasteners are used. Related, authenticated tests carried out earlier have proved that the claimed herein self-locking and self-tightening features are indeed attainable. Proposed related manufacturing processes and operation plans involving a combination of automated CNC high technology (Lasers) and CNC low technology (mechanical equipment, dies, tools, fixtures, etc.) may result in these high quality products produced at relatively reasonable cost.
