DEFINITION

Classification: 439/665

Having mutilated, irregular, interrupted, or discontinuous contact thread:

(under subclass 662) Coupling part wherein the screw threading disposed on the screw-thread-coupling contact is broken, deformed, or of a noncontinuous helical configuration.

(1) Note. The discontinuity of the screw threading on a cylindrically-shaped contact shaped shell or tube may be due to the contact shell or tube being composed of an assembly of two or more separate sections which do not touch one another when they are mounted together to form the cylindrical shape.
