  • Patent number: 4518276
    Abstract: Devices have been used to compensate for misalignment between adjacent members and establish subsequent aligned assembly. These devices used tight tolerance, compound eccentric bushings or offset frusto-conical surface in attempting to provide a fixed aligned position. These devices are expensive and difficult to align. The subject bolt-on dowel provides a simple inexpensive solution to positioning of a first member relative to a second member. The bolt-on dowel includes a cylindrical spacer slidably fitted within a bore of the first member with the first end being in abutment with the second member, and a fastening member securing the spacer to the second member in a fixed position.
