Patent ID: 8337129

Claim:
An apparatus for locking and flagging a wheel nut, the wheel nut being rotatable about a central axis to a secured position, the apparatus comprising: a substantially cylindrical body having a toothed central bore therein sized to closely surround and engage a periphery of the wheel nut, said cylindrical body having a gap substantially aligned with said central axis, wherein said gap is disposed between a pair of opposed arms, extending between proximate and distal ends, said proximate ends being secured to said cylindrical body and said distal ends forming said gap therebetween, wherein said arms are cantilever towards each other and are radially biased towards a center of said toothed central bore and form a portion of said central toothed bore therein so as to permit said cylindrical body to be radially expandable; a first extension extending perpendicularly from said body, said first extension having an indicator thereon; and a second extension extending perpendicularly from said body to an opposed side thereof, said second extension having a distal end adapted to overlap and engage with a first extension of an adjacent apparatus for locking and flagging an adjacent wheel nut so as to cover said indicator of said adjacent apparatus when said wheel nut is in the secured position.
