Abstract
A low profile ratchet wrench has an opening formed through the head of the wrench. A pawl module having a body, a detent mechanism, a reversing lever and a pawl is received in a portion of the opening. A socket having a first portion with circumferential gear teeth and an integral second portion having an axially formed opening, is removably received in the opening in the head adjacent to the pawl module. Teeth on the pawl in the pawl module cooperate with the gear teeth on the socket. The socket is removably retained in the opening in the head. A method of assembling and using the low profile ratchet wrench is described. The pawl module is used in a breaker bar.
