DEFINITION

Classification: 411/116

Head or nut side face held by discrete member (e.g., side lock):

(under subclass 81) Device wherein the other element, or at least one of the plurality thereof, comprises a member which engages the substructure and which has at least one portion for contacting (a) either at least one planar, side surface of a plural-sided bolt head or nut or at least one formation (e.g., a corner formed by the junction of adjacent side surfaces, a tooth, etc.) on the side of a bolt head or nut or (b) a corresponding flat side or sidewardly facing formation on a second, other (i.e., an additional) element which is located on the axis of, and is caused to turn with, the bolt head or nut, which additional element substitutes for the bolt head or nut insofar as engagement with the member is concerned.

(1) Note. The coaction of the member with the substructure is an essential aspect of the member's capability for restricting rotation of the bolt or nut relative to the substructure.
