ABSTRACT:
A detent ball is retained in a recess against a bias spring by deforming the material around the open end of the recess radially and axially inwardly of the recess to define a retaining lip to hold the ball in place, the lip having a substantially part-spherical outer surface. The deformation is accomplished by an embossing tool having a part-spherical embossing surface which converges from an end wider than the recess to an end narrower than the recess. A part-spherical cavity in the end of the embossing tool accommodates the ball during the deformation process.
