DEFINITION

Classification: 411/309

Resulting in the deformation of one thread by the other:

(under subclass 308) Device wherein one of the threads distorts the other thread to an extent which exceeds its elastic limit.

277+, for deformation of the thread of an internally threaded element (i.e., a nut) resulting from radially inwardly distortion of the element.

285+, for deformation of the thread of an internally threaded element (i.e., a nut) resulting from axial distortion of the element.
