DEFINITION

Classification: 411/110

Member comprises a longitudinal key:

(under subclass 103) Device wherein the member comprises one or more elongated elements which extend generally parallel to the longitudinal axis of the bolt or nut and which engage the substructure at the hole or pocket formed therein and also engage whichever of the bolt or nut is held in the hole or pocket.

Most typically, the nut takes the form of an internally threaded sleeve which is recessed into the substructure, and the key is at least one bar or rod inserted at the juncture of the outer surface of the sleeve with the wall of the hole or pocket; if two or more keys are utilized, they are spaced apart therearound.
