DEFINITION

Classification: 411/259

Comprising a thread lock:

(under subclass 190) Device wherein the rotation restricting means comprises either the thread structure of one of the other of the threaded elements, or the interaction of the threads of one element upon the threads of the other element, or the action of an additional element upon the threads of one or the other or both of the threaded elements.

SEE OR SEARCH THIS CLASS, SUBCLASS:

167, for a threaded fastener (i.e., a bolt or nut) and means for restricting the rotation thereof relative to a coacting substructure and wherein the means comprises the structure of the bolt, nut or substructure and further wherein a bolt-to-nut thread lock is also provided; see also the search notes of that subclass for other subclasses of this class which include a thread lock.

222+, for a coupled bolt and nut which includes a rotation restricting member which coacts with the axially outwardly facing portion of the internally threaded element and wherein

that member is an additional internally threaded element, in which art, it may be observed, the action of one internally threaded element upon the other, and the resultant reaction of each upon the thread of the externally threaded element, often is the basis for the coupling achieved.
