DEFINITION

Classification: 411/167

Lock nut type on fastener:

(under subclass 166) Device wherein there is also provided, on one or the other, or both, of the bolt or nut, thread structure of a kind which serves to couple one to the other to restrict rotation therebetween.

(1) Note. The thread lock of this subclass ordinarily is separate from and not directly related to the means by which the bolt or nut is restricted in rotation relative to the substructure.

SEE OR SEARCH THIS CLASS, SUBCLASS:

105, for the reference to a thread lock appearing in (2) Note thereof.

106, 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 includes a restricting member and further wherein the member is preassembled with the substructure at a through-passage or a recess therein for holding a bolt or nut in coaxial relation with the through-passage or recess and additionally wherein means (e.g., a thread lock) is provided for coupling the bolt and the nut to one another.

118, 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 includes a restricting member and further wherein the bolt or nut, or a coaxial adjunct therefor, has a sidewardly facing flat or formation engaged by a portion of the member (e.g., a side lock) and additionally wherein a thread lock is provided for coupling the bolt (or nut) to a complementary nut (or bolt).

168, for a device of this area (166+), but wherein the means includes or consists of a thread lock between a bolt and a substructure, the latter functioning as a nut insofar as the bolt is concerned. 259+, for a threaded bolt and nut and means for coupling them against relative rotation and wherein the means is proximate to and involves the region of their threaded interengagement (i.e., a thread lock).
