Fastener with discrete head cap
First Claim
1. A fastener, comprising:
- a fastener body having a first end, a second end and an intermediate portion extending between said first and second ends;
a threaded portion proximate to said first end;
a tool engaging surface on said intermediate portion, said tool engaging surface having a shaped pattern adapted to receive a matching wrench or key that engages and rotates said fastener;
a head cap receiving bore at said second end;
a discrete head cap bearing surface surrounding an outside end of said head cap receiving bore;
a head cap retaining surface on said head cap receiving bore;
a head cap having a rigid base and a central stem extending from said base;
said head cap stem being disposed in said head cap receiving bore;
said head cap base having a body bearing surface at a base of said stem in contacting or near-contacting engagement with said head cap bearing surface;
said head cap base further having a head cap outer surface; and
a head cap retainer interconnecting said central stem and said head cap retaining surface, said head cap retainer comprising a material of sufficient strength and rigidity to retain said head cap on said fastener body in a high-strength, axially non-deformable interconnection that holds said head cap in a substantially fixed and immovable axial position.

Abstract
A threaded fastener comprises a fastener body having a threaded portion, a tool engaging surface, and a head cap receiving bore. The head cap receiving bore has a head cap bearing surface and a head cap retaining surface. A head cap has a rigid base and a central stem extending from the base. The head cap stem is disposed in the head cap receiving bore. The head cap base has a body bearing surface in contacting or near-contacting engagement with the head cap bearing surface. The head cap base further has a head cap outer surface. A head cap retainer interconnects the head cap stem and head cap retaining surface. The head cap retainer comprises a material of sufficient strength and rigidity to retain the head cap on the fastener body in a high-strength, axially non-deformable interconnection that holds the head cap in a substantially fixed and immovable axial position.

- 22. A fastener comprising a fastener body and a decorative head cap rotatably mounted on an end face of said body bearing visual information content whose appearance is dependent on its rotational orientation, said decorative head cap being rotatably positionable when said fastener is installed at an arbitrary rotational position in order to orient said visual information content in a desired orientation, said fastener further including a tool engaging surface on an intermediate portion of said body that is adapted for engagement by a wrench or tool without removing said head cap.
