A jam nut is a thin locking nut threaded onto a bolt or stud alongside a primary nut to prevent the assembly from backing off under vibration or cyclical load. It works by creating a clamping force between itself and the primary nut, effectively locking both in position. When a jam nut is missing, damaged, or undersized, fastened assemblies can loosen progressively during operation, leading to misalignment, accelerated wear on mating components, or mechanical failure at the connection point.
