What is the difference between a torque wrench and a lever arm torque multiplier?

• A. Lever arm torque multiplier increases torque with mechanical advantage.
• B. Both tools provide equal torque capabilities; selection depends on preference.
• C. A torque wrench provides direct torque; lever arm torque multiplier increases torque with mechanical advantage; use per manual.
• D. A torque multiplier can measure torque more accurately than a torque wrench.

Answer: (C)

Torque control and measurement differ: a torque wrench is designed to apply and verify a specific, calibrated torque at the fastener. You set the value and the wrench indicates when that exact torque is reached, giving precise control over the tightening. A lever arm torque multiplier uses mechanical advantage to multiply the input torque you apply, producing a much higher output torque at the fastener without requiring immense force. It doesn’t inherently measure the output torque unless it has a built‑in gauge or is used with a separate torque meter, so you follow the manual to ensure proper use and accuracy. In short, the torque wrench provides direct, measured torque, while the lever arm multiplier increases torque through leverage (with measurement often needing additional equipment).
