DEFINITION

Classification: 411/274

Having an element, or with a discrete member, adapted to cant the assembly:

(under subclass 259) Device wherein either the internally threaded element, the externally threaded element, or an additional member in association therewith, is wedge-shaped, has eccentrically arranged protuberance means thereon, or is otherwise adapted to cause the elements in the assembly to become tilted with respect to each other, thereby producing a binding of the mating threads.
