A mechanical separation system is disclosed which includes a stud member and a stud housing maintained in mating engagement by a piston. The stud member has a plurality of externally-threaded segments fingers which can be formed in an overall conical shape so that the major diameter of the threaded portion of the conically-shaped fingers is less than the minor diameter of the corresponding internal threads in the stud housing. The piston is positioned within the segmented fingers of the stud member to force the fingers radially outwardly so that the threaded portions mate with the corresponding threads in the stud housing. Separation of the stud member from the stud housing is accomplished by displacing the piston to allow the stud fingers to move inwardly to assume a conical shape. The externally threaded portion of the stud member is thus disengaged from the internal threads of the stud housing to permit separation of the stud member from the stud housing. In an alternative embodiment, the fingers of the stud member are not formed into a conical shape prior to use, but the energy imparted to the fingers as they are threaded into the stud housing is sufficient to cause the fingers to be deflected inwardly and to disengage from the housing when the piston member is forced out of contact with the end portions of the fingers.
