ABSTRACT:
A fastening apparatus is adapted to be inserted and removed from one side of a work piece having an opposite side which is substantially inaccessible to a worker. A first, externally threaded member is threadingly engaged with a receiving structure, and a second member is inserted within corresponding seats or grooves for interlocking the two members. In the preferred embodiment diverting seats are provided for forming the second member into locking engagement between the receiving structure and the first member. In one embodiment, seat structures are provided for engaging frangible panels or the like for high temperature applications.
