ABSTRACT:
A locking system including a combination of a multistrand locking wire and a ferrule bearing an identification mark for preventing threaded fasteners on a device from loosening due to vibration, each of the fasteners having an aperture for receiving the locking wire. The ferrule with an identification mark serves as a seal for identification and for preventing tampering with the device. The identification mark can be either premarked on the ferrule before system installation, or be applied to the ferrule during system installation, such as by shaping the crimped deformation on the ferrule into an identification pattern.
