ABSTRACT:
Bushings are embedded within a production drill plate to replicate the hole pattern of a master hole pattern plate. The exterior surface of each bushing is threaded, as is the wall of a receiving hole in the production drill plate. The pitch of the bushing and hole are the same but the pitch diameters are somewhat different so that the threads of the bushing are loosely engaged within the threads of the hole. When the bushing is potted in a properly aligned position, the containment potting material becomes compressed in the thread engagement area thereby resisting axial displacement of the bushing.
