ABSTRACT:
An apparatus for providing a self-adjusting tie down includes a bolt extending into a foundation and a nut on that bolt which is supported by two shims, one of which can move relative to the other. A spring exerts substantially constant force on the movable shim, preventing gaps from forming between the nut and the shims underneath.
