Torque multipliers are devices that increase the amount of torque applied to fasteners and other applications where a high amount of torque is needed. They use a planetary gear system to increase a low input torque and apply it to a fastener.
Torque multipliers are hand tools which may use manual, electric, or pneumatic power to achieve increased torque. Powered multipliers feature adjustable torque by means of a regulator, while manual tools use a torque wrench to determine the desired output torque.
