ABSTRACT:
A series of high security fastener constructions feature rotatable anti-theft shrouds mounted on locking wheel nuts and wheel bolts designed for vehicular wheels. Each construction features (1) a fastener body having a first body end adapted to accommodate a key receiving pattern or member, a second body end having thread pattern extending therefrom, and a shroud receiving portion located between the first and second body ends, (2) a shroud concentrically mounted on the shroud receiving, and (3) a shroud retaining system for retaining the shroud for rotation relative to the fastener body such that the shroud will rotate under an applied torque prior to the fastener rotating when it is installed at a design installation torque. Exemplary shroud retaining systems include (1) designs in which the shroud is retained by interference engagement of its inner side with the fastener body, (2) designs in which the shroud is retained by staking or swaging to the fastener body, and (3) designs in which the shroud is retained by first and second retaining members that are mounted on the fastener body in facing relationship with first and second annular faces of the shroud. The shroud can be substantially tubular, or it can be thickened at one end to provide a security enhancement feature.
