Abstract: The present invention comprises a lug nut which has two separable portions connected by a frangible neck, wherein a first portion engages the threads of the stud, and a second portion provides a surface adapted to engage a wrench so that the lug nut may be driven into the stud. When the stud-engaging first portion has been threaded onto the stud and sufficiently tightened, continued application of torque cause the frangible, wrench-engaging second portion to shear off from the stud-engaging first portion. The stud engaging portion has an annular notch which is adapted to engage a snap ring located in the wrench-engaging portion. After the wrench-engaging portion is severed from the stud-engaging portion, the wrench-engaging portion is then reversed and positioned onto the stud-engaging portion. When so positioned, the snap ring engages the notch, which rotatably secures the wrench-engaging portion to the stud engaging portion.

Abstract: There is disclosed a bracing bar assembly for use in connection with a cargo container which includes a tubular freight bar having a hollow interior, a pair of upper and lower interiorly formed rails extending the length of the brace bar forming lock channels at each end of the brace bar, a lock assembly formed by a main body portion having a horizontally elongate configuration and sized so as to be slideably positionable within the lock channel, the exterior end of the main body portion of the lock assembly provided with a latch mechanism including a lower notched end and an upper end having a spring loaded finger latch and brace bar and lock assembly cooperating lock holding means to hold each of the lock assemblies in position within the lock channels of the brace bar to complete the assembly.
