DEFINITION

Classification: 411/103

Multipart nut assembly with one member attached to structure or substructure:

(under subclass 81) Device wherein the other element, or at least one of a plurality thereof, comprises a member which is connected to, or otherwise held in contact with, the substructure adjacent to, at or within either a hole which penetrates the substructure or a pocket which enters the substructure to an extent less than its thickness and which member functions to locate and support a single bolt or nut in such a manner, relative to the substructure, that the longitudinal axis of the bolt or the nut is in alignment with the principal axis of the hole or pocket, the purpose of the arrangement being to place the bolt or nut in a proper position for receiving the nut or bolt, respectively, which is intended to be placed in threaded engagement with it.

(1) Note. In a few instances, the member is an assembly of plural elements functioning as one.

(2) Note. In locating and supporting the bolt or nut relative to the substructure, the member restricts, or

assists in restricting, the bolt or nut against axial movement in addition to its usual function of restricting, or assisting in restricting, the bolt or nut against rotational movement.
