US Patent 10260551 Self-actuating lock nut and assemblies

The present invention relates to an assembly of a self-locking hex head screw and a self-locking hex nut that use parallel screw threads of one or various types that lock against each other upon applying a torque. The resulting counteracting torque forces provided by the screw thread types are further enhanced by applying a physical lock using press fit surfaces on the nut and finally when a snap ring is deployed to that prevent these threads from prying loose later on.
