DEFINITION

Classification: 411/90

Member extending between and engaging flat formed on side of each of a plurality of flat sided bolts or nuts (e.g., side lock):

(under subclass 81) Device wherein the other element, or at least one of a plurality thereof, comprises a member in the nature of either a single piece of material or a plurality of pieces related in some fashion to one another, which member is positioned in such a manner that a principal surface

thereof occupies a plane which parallels, or nearly parallels, that surface of the substructure with which it is in a facing relationship, and wherein the member includes a portion (e.g., an arm or lip extending normally to the principal surface of the member) for making contact with one or more planar regions formed on the exterior of, and extending parallel to the principal axis of, each of a plurality of bolts or nuts.

(1) Note. In the instance of a bolt, the planar region ordinarily is located on the head, rather than the shank.
