DEFINITION

Classification: 411/999

WITH RETAINER (E.G., TETHER):

(under the class definition) Art collection wherein a mass, other than the cooperating threads on the bolt-shank or the nut or substructure, is provided to prevent complete separation or loss of an assembled bolt, nut and substructure, as, e.g., by tethering means, or prevent their axial or endwise separation while permitting rotation.

(1) Note. The retainer does not prevent the rotation of the bolt or nut and may even allow its complete withdrawal, the retainer merely preventing the bolt or nut from being lost by means as, e.g., a flexible connector.
