DEFINITION

Classification: 411/168

Including a lock thread:

(under subclass 166) Device wherein the rotation restricting means either includes as a portion thereof, or else consists wholly of, thread structure, on one or the other or both of the bolt and the substructure with which it is in threaded engagement, of a kind which serves to couple one to the other.

(1) Note. The substructure functions here as a nut insofar as the bolt is concerned.
