Abstract
A flanged connection for shafts or tubes includes abutting flanges at adjoining ends of the shafts or tubes and also includes aligned bores in the flanges. Fasteners extend through the bores in directions parallel to the axes of the shafts or tubes. The fasteners are radially expandable into clamped conditions in which they abut and exert radial pressure against the bores in the flanges. This eliminates the play between the two adjoining flanges, which play stems from necessary initial clearances between the fasteners and bores to allow for insertion of the fasteners into the bores.
