  • Patent number: 6431602
    Abstract: A coupling apparatus for spanning a gap between a first structure and a second structure and fixedly coupling the first and second structures together. The coupling apparatus includes first and second coupling structures, an attachment member and a coupling member. The first coupling structure has an internally threaded cavity and is fixedly coupled to the first structure. The second coupling structure has an externally threaded body and an abutting flange. The externally threaded body threadably engages the internally threaded cavity, permitting the first and second coupling structures to cooperate to span the gap between the first and second structures such that the abutting flange abuts the second structure. The attachment member includes a threaded portion which extends through the first and second coupling structures and threadably engages the coupling member.
