ABSTRACT:
A button device has a head member and a back member joined therewith, the head member having a central cavity dimensioned to receive an insert member with a press-fit. The insert member is generally dome-shaped with its peripheral wall upwardly tapered. The cavity is defined by an inner wall initially upwardly flared but deformed to taper when a peripheral ridge is clamped against the insert member by a punch capable of producing a clamping pressure of a bidirectional vector.
