Abstract
A fastener system for retaining a loose elongate fastener in a counterbore, including an elongate fastener, such as a bolt, having a head for being received and retained in a counterbore in a structure and in generally flush relation to a surface of the structure surrounding the counterbore, and a retaining member for being secured to the structure proximate the counterbore and overlapping the counterbore to trap the loose fastener in the counterbore.
Claims12
A fastener system for retaining an elongate fastener in a counterbore, comprising:
- (a) a structure having a surface, a bore hole, a counterbore defined in the surface around the bore hole, a threaded hole parallel to and spaced from the bore hole, and a recess defined in the surface around the threaded hole, the recess adjacent to and communicating with the counterbore;
- (b) an elongate fastener having a shank positioned in the bore hole, an enlarged head attached to the shank and positioned in the counterbore, and a recess defined in the head and aligned with the recess defined in the surface of the structure;
- (c) a retaining member at least partially overlapping both the recess defined in the surface of the structure and the recess defined in the head of the fastener, the retaining member having a hole defined therethrough;
- and
- (d) a threaded connector extended through the hole defined through the retaining member and threaded into the threaded hole of the structure, the threaded connector having a head attaching the retaining member to the structure such that the retaining member retains the head of the fastener within the counterbore.

A fastener system for retaining a bolt in a counterbore, comprising:
- (a) a structure having a surface, a bore hole, a counterbore defined in the surface around the bore hole, a threaded hole parallel to and spaced from the bore hole, and a recess defined in the surface around the threaded hole, the recess adjacent to and communicating with the counterbore;
- (b) a bolt having a shank positioned in the bore hole, an enlarged head attached to the shank and positioned in the counterbore flush with the surface of the structure, and a recess defined in the head and aligned with the recess defined in the surface of the structure;
- (c) a retaining member at least partially overlapping both the recess defined in the surface of the structure and the recess defined in the head of the bolt, the retaining member having a hole defined therethrough;
- and
- (d) a threaded connector extended through the hole defined through the retaining member and threaded into the threaded hole of the structure, the threaded connector having a head attaching the retaining member to the structure such that the retaining member retains the head of the bolt within the counterbore.

A method of retaining an elongate fastener in a counterbore, comprising the steps of:
- (a) providing a structure having a surface, a bore hole, a counterbore defined in the surface around the bore hole, a threaded hole parallel to and spaced from the bore hole, and a recess defined in the surface around the threaded hole, the recess adjacent to and communicating with the counterbore;
- (b) providing an elongate fastener having a shank, an enlarged head attached to the shank, and a recess defined in the head;
- (c) positioning the shank of the fastener in the bore hole and the head of the fastener in the counterbore with the recess defined in the head aligned with the recess defined in the surface of the structure;
- (d) providing a retaining member having a hole defined therethrough;
- (e) placing the retaining member into a position at least partially overlapping both the recess defined in the surface of the structure and the recess defined in the head of the fastener;
- and
- (f) retaining the head of the fastener within the counterbore by extending a threaded connector through the hole defined through the retaining member and threading the threaded connector into the threaded hole of the structure such that a head of the threaded connector attaches the retaining member to the structure.
