DEFINITION

Classification: 411/104

Through-passage or recess having laterally extending entry for inserting member and nut:

(under subclass 103) Device wherein the substructure additionally includes a cross passage which enters the hole or pocket from a side thereof, which cross passage is for the purpose of moving the member, and a nut held therein or thereon, into alignment with the axis of the hole or pocket, and, hence, into alignment with the bolt which will be placed into the hole or pocket.

(1) Note. The "width" of the member-nut assembly is greater than the diameter of the hole or pocket, thus, necessitating the provision of a cross passage for inserting the assembly into bolt-receiving position.

(2) Note. The member frequently holds the nut loosely in order to allow for limited realignment thereof when the bolt is introduced.

(3) Note. The member-nut assembly hereof is often identified as a "barrel nut".
