A lighter-duty torque arm for assembly screwdrivers is offered. The arm has been value-engineered to provide reliable service at an attractive price. It improves production efficiencies and product quality by reducing operator fatigue and by limiting operator influence on the assembly process. The parallel arm design keeps the tool perpendicular to the work surface. The arm also helps absorb torque to reduce potential for operator injury to arm, wrist, or hand. Pneumatic or electric inline drivers can be used with the arm (electric tools require an adaptor).
