Abstract
A system for clamping a bellows assembly of a mechanical seal to its flange in the minimum radial and axial space which comprises the use of set screws, the threads of which are received in openings defined in part by a body flange and in part by a bellows support ring. The portion in the support ring is threaded while the remainder is not threaded. The threads in the threaded opening portion may match those of the set screw, i.e., helical, or may be merely parallel, i.e. not helical. In the latter, the arc of contact between the threads is relatively small.
