Lock nut.

摘要

The present invention provides a self-cleaning beam arrangement for threaded lock nuts. Each beam (22) is constructed and arranged such that opposing side walls (27,28) of adjacent beams are oriented so as to diverge outwardly away from each other. Movement of the plurality of beams between a free state and locking state combines with the diverging orientation of the side walls to eject or move debris outwardly from the area between the beam side walls.
