Abstract
A wire mesh filter screen has a flat disc shape and is seated on a flat bottom counterbore in a threaded fitting. A circular knife edged punch pierces a ring of material from the counterbore wall surrounding the disc periphery. A second flat punch axially deforms the ring over the disc periphery to securely retain the screen in the fitting.
