ABSTRACT:
A fastener assembly comprising in overlying, stacked relationship a flat washer, an elastically deformable washer and a nut all enclosed in a shroud which assures all components of the assembly are used and in their proper order. The shroud is fashioned with a retaining lip at one end which, as the assembly is tightened, causes the shroud to retreat from the assembly to prevent its retention between the flat washer and the surface about the threaded stud to which the assembly is fastened. By the inclusion of an additional lip the retention of the shroud, after the torque limiting device coupled to the nut has been removed, can be assured.
