Williams High Tensil Tie Rods are available in all diameters shown, with lengths from 3” to 20’-0”. They are available all-threaded, thread one end, or threaded both ends. Short length tie rods threaded both ends under 2’-0” are usually crimped to prevent rotation in the concrete during removal of the Shebolt. Ties threaded each end allow easy spot checking of the connection, to insure proper engagement.
