Class Information
Number: 411/310
Name: Expanded, threaded, driven, headed, tool-deformed, or locked-threaded fastener > Having structure to restrict rotation of threaded, mating pieces (e.g., nut lock) > Comprising a thread lock > Involving dissimilarities in the sectional configuration of the threads > Resulting in the deformation of one thread by the other > By integral, interference-producing deviations from a standard thread shape
Description: Device wherein the distortion is produced by the presence, on at least one of the threads, of regions, integral with the material of the thread, which extend beyond, at one or more locations, the cross-sectional shape of a standard (e.g., a 60°) thread.
