Abstract: A method and apparatus for patching a hole in a panel without the use of a bonding agent or the aid of a welding apparatus. The method encompasses the placing of a patch within the confines of a hole. The patch is of a configuration which is within a close tolerance of the hole and of the same thickness as the thickness of the panel. This provides a flush inside surface and a flush outside surface upon the completion of the repair. The patch is temporarily secured with supports and bores are drilled around the periphery of the patch which communicate with both the patch and the panel. These bores are tapped to accommodate a segmented threaded rod. The depth or thickness of each threaded segment is almost equivalent to the thickness of the panel. The segmented threaded rod is threaded into the hole until it is flush with the inside surface. Each consecutive segment is separated by a core.

Abstract: A one piece item of stainless steel or other material suitable for permanent placement in the human body, forms the eye and shaft of an eyebolt by a combination of two shell-like portions, each having threaded bosses at distal ends thereof. The distal ends are placed around a spinal rod simultaneously with insertion of one of the shell-like portions through the yoke of a spinal column connecting hook device. Then the bosses are brought toward each other and the two bosses combine to form a bolt on which a nut is received and advanced along the threads. As this is done, it forms the eye of the eyebolt and it is brought into cooperation with the hook device to clamp tightly on a spinal rod with which the eyebolt is used. The two threaded bosses have interfitting, and thus mating, rib and groove to establish and maintain alignment of the threads of the two bosses to facilitate reception of the nut on the bosses.

Abstract: A fastener system is providing having a male threaded member and a female threaded member with arrangements for achieving a locking connection between the parts to prevent relative rotation of the parts due to vibration.
