DEFINITION

Classification: 411/82

MADE, MODIFIED, OR PREPARED FOR SETTABLE MATERIAL:

(under subclass 81) Device wherein the means comprises or includes a quantity of a substance which is hardenable from a soft or flowable, as-applied state into a state in which it serves to affix, or assist in affixing, a bolt or a nut, and, in some instances, one or more additional elements that are associated with the bolt or nut, to a substructure.

(1) Note. Exemplary of the substances are (a) adhesives for exerting a force which tends to keep two or more parts from separating such as (1) a flowable as applied but air hardenable material in the nature of a glue, (2) a normally hard but heat-softenable and subsequently rehardenable material in the nature of solder, or (3) a predisposed film or layer of material which, while essentially set up by the time of its use, remains tacky on its surface, (b) compositions such as weld rod or a chemical solvent which, with or without, respectively, the assistance of heat, molecularly intermingle with and unite two or more parts, and (c) a material which may be flowable when applied but which undergoes an increase in volume upon setting up and thus forces two or more parts into relatively rigid engagement with one another.

SEE OR SEARCH THIS CLASS, SUBCLASS:

171, for a threaded fastener (i.e., a bolt or nut) and means for restricting the rotation thereof relative to a coacting substructure wherein the means comprises the adapting of the bolt or nut to be fused directly to a substructure (i.e.,

without the use of additional material) (e.g., a weld nut).

257, for a threaded bolt and nut and means for coupling them against relative rotation wherein the means includes material which may be a metallic coating or a quantity of fusible metal.

258, for the coupled bolt and nut mentioned in the reference to subclass 257 above, but wherein the means includes a settable material.

376, for a headed fastener with a nut, washer, securing means or cap and wherein the element which is in addition to the fastener is a cap which is attachable by fusion bonding.
