Abstract
A hand tool of the type having a variable torque-limiting in-line drive with a handle having a cavity and a drive bit disposed in the cavity. Over-ride drive members are disposed in the cavity and a spring exerts a force on the drive members for transmitting only a maximum force to a bit in the tool. A variable control adjustment is on the tool and is used to apply a varying force to the spring and thus control the amount of maximum torque to be transmitted.
