Abstract
An adjustable, torque-limiting driver for a tool having a radially extending handle that houses a cam member and a pair of plungers. The plungers are biased against the housing and provide variable resistance for the cam member. The arrangement of the cam member and the plungers reduces the wear on the various parts of the driver and extends the life of the driver.
