Abstract
A double end stud has a shank member including a central slide shank portion and threaded portions formed coaxially on both axial ends of the slide shank portion. The threaded portions are externally threaded in opposite directions. The double end stud also has a nut member carried by the slide shank portion of the shank member slidably in the axial direction but not rotatably with respect to the slide shank portion. In use, the nut portion is moved axially as the threaded portions are screwed into female thread portions of the two structural members to be connected, so that the depth of penetration of the double end stud into both structural members are optimized to ensure a high strength of connection between these structural members.
