The Six-Wing® frangible collar is recognizable by the six-faceted, semi-spline arrangement of wings around the collar base. These collars are used in high strength applications, typically on fighter aircraft. Special tapered spline sockets were developed to remove these collars.When fitted into the flat box ratchet handle, these sockets provide easy removal, while at the same time preventing re-installation or re-use of the removed collars. New collars must be used to insure proper torque. 6-Wing® collar removers are available as an individual socket or a complete ratchet tool assembly.
