	This subclass is indented under subclass 198. Subject matter wherein the component is structured such that it may be readily retracted toward the axis of the device to allow its withdrawal from a formed hole without reversing any rotary motion of the device.

202	... Cam core:

	This subclass is indented under subclass 201. Subject matter wherein the device is actuated by a rotary mechanism which engages a eccentrically shaped surface axially or concentrically mounted relative to the device.

203	... Wedge core:

	This subclass is indented under subclass 201. Subject matter wherein the device is actuated by a triangular shaped or conical surface which engages the device.

204	.. Thread swage:

	This subclass is indented under subclass 198. Subject matter wherein the device is capable of forming screw threads by shaping cold metal.

205	. Bolt or rivet heading punch:

This subclass is indented under subclass 183. Subject matter wherein the component is specially adapted for forming a head on either: (A) an externally threaded fastener structured to cooperate with an internally threaded fastener, or (B) a fastener provided with an end structure consisting of a polycrystalline metallic grain structure which when subjected to an externally applied force is plastically flowable.

206	. Nut or washer arbor:

This subclass is indented under subclass 190. Subject matter wherein the component is specially adapted for supporting a internally threaded fastener or an annular element adapted to be placed beneath the bearing surface of a bolt head, nut, or similar article during a forming operation.
