ABSTRACT:
The fixture or dowel pin has an axial opening including progressively smaller tapered sections alternating with progressively smaller cylindrical threaded sections. Screws having corresponding tapered tops and threaded sections fit respectively into the sections of the body and, after the pin is inserted in the openings of two plates to be immobilized, the respective screws are tightened to expand the pin body in zones outward from the respective screws and immobilize the pin and plates surrounding the zones.
