Abstract

Official abstract text for this publication.

A power tool includes a motor and an output assembly configured to receive torque from the motor. The output assembly includes an anvil having a cylindrical body portion, an output member configured to engage a socket, and a curvilinear transition portion that tapers between the body portion and the output member. The transition portion defines a radius in a plane containing a rotational axis of the anvil that is greater than 1.5 mm. The output assembly also includes a pawl that is moveable between a first position in which the pawl is operatively coupled to drive the anvil in a first direction and a second position in which the pawl is operatively coupled to drive the anvil in a second direction opposite the first direction.

First claim
