A novel head device generally consisting of at least one aperture that is capable of excepting different sizes of safety wire, at least one cam-locking lever, which may incorporate a spring return mechanism, is disclosed. The body may be rotated by a mechanical means which twists the safety wire. In preferred embodiment, the various elements of the safety wire twister device are each configured with means of limiting torque or twists of safety wire to eliminate possibility of over torqueing or twisting of safety wire.

The present disclosure relates to a fastener and cap that are used as part of a fastener system to lock the fastener in place relative to a compatibly threaded shaft. In a preferred embodiment, the locking feature is utilized in vehicles, such as in aircraft.
