Abstract: A tool assembly in which the tool retainers are provided with spring loaded plungers which snap into place in detents provided in the tools and are then locked in the detents by set screws engaging the shanks of the plungers. This prevents inadvertent displacement of the tools, particularly punches, from their retainers, especially displacement due to jarring or vibration during manufacturing of the tool assembly. The retainers are attached to their respective shoes by bolts having tool engageable sockets in both their leading ends and their heads. This facilitates manufacture of the tool assemblies while permitting replacement of the tool retainers without removing the shoes from the press in which they are mounted. Additionally, a stripper plate may be mounted by means of bolts having tool engageable sockets in either end to permit the plate to be removed from the press without removing the shoe to which the stripper plate is attached.
