Jumbo angle wrenches are essential to the heavy duty mechanic working on the trucks, tractors and heavy equipment. He may use a long heavy wrench to break loose a large fastener and a short angle wrench to finish the job faster and easier. The light and short angle wrenches reduce operator fatigue after a long day of repeated use. Many mechanics use the short angle wrenches exclusively when working on hydraulic lines that don't require high torque.
