ABSTRACT:
The present disclosure relates to an anvil, an anvil and socket combination and an anvil attached to a power tool. The anvil structure includes a drive head with an end and a body portion having a channel spaced there between. A friction ring is retained in the channel. Flats are provided on the end and on the sides of the end and the square portion in a coordinating alignment such that the flats generally lie in the same plane. The ring retained in the channel between the end and the portion at least partially extends relative to the flap. A transition cone is provided on the anvil for distributing impact load. Additional, relief grooves are provided on corners of the polygon portion to help further relieve stress in the anvil structure.
