An adjustable handle system for fastening tools that drive threaded fastener into materials. The present invention allows the handle of fastening tools to change shape so that the tool can function in a confined environment. The handle system is made up of at least two handle portions that are interchangeable due to a common form of detachable connection between the handle portions and drive head. The common connections are detachable in that portions of the handle system can be connected and disconnected from each other with minimal effort. Interchangeability of the differently configured portions enables the handle system to take on many different configurations, thus allowing the fastening tool to function in a variety of confined environments.
