摘要： A load-bearing member such as a beam, column, girder or post comprises an elongated body defining a rigid structure for bearing a load. A hollow fastener extends through the body from a first side of the body to a second side of the body. The hollow fastener, which may be a hollow bolt, nail, lag screw or threaded shaft, defines a passageway through the load-bearing member for insertion of a cable, wire, tube or pipe. This obviates the need to drill the beam or column, which can compromise its structural integrity.
