Expanded, threaded, driven, headed, tool-deformed, or locked-threaded fastener

SECTION I - CLASS DEFINITION

This class is the locus for the following types of fasteners when they are adapted for general use and are not sufficiently limited to use with special articles or structures as to require classification therewith:

A. An anchoring-type or holding-type fastener which expands upon receiving a driven fastener or when driven by a tool;

B. A tool driven externally threaded fastener (e.g., bolt, screw);

C. A tool driven internally threaded fastener (e.g., nut);

D. An impact driven fastener (e.g., nail, staple);

E. A tool driven or discrete (i.e., not affixed to workpiece), headed, elongated-shank fastener adapted to be moved along its longitudinal axis into coaxial apertures in a workpiece, wherein the headed, elongated-shank fastener is secured by either (1) a deformable end (e.g., rivet), (2) means other than threads requiring rotation for engagement (e.g., Dzus-type or quarter-turn fastener), (3) pivotable securing means (e.g., toggle bolt), (4) retractable securing means (e.g., ball detent fastener), or (5) a separate retaining element; and
