ABSTRACT:
Apparatus for securing together structural members includes a stud threaded at both ends and a stud sleeve threaded at both ends. The stud and stud sleeve are coaxial with the stud extending through the stud sleeve and beyond the ends of the stud sleeve. The threaded stud ends and the threaded sleeve ends are separately threadedly connected to the structural members so that both the stud and stud sleeve apply forces to the structural members to secure them together. No significant transfer of load between the stud and the stud sleeve will occur.
