Which item is used to help apply controlled torque when tightening lug nuts on wheels?

• A. Torque Wrench
• B. Torque Multiplier
• C. Torque Stick
• D. Impact Driver

Answer: (B)

The key idea here is applying a precise, controlled torque to the wheel fasteners. A torque multiplier is designed to multiply the input torque you apply, which lets you reach very high output torque without needing extraordinary force. This makes it possible to tighten lug nuts to high specifications safely and with better control than you could with your hands alone or with a simple impact tool. In practice, you’d typically use a torque multiplier in combination with a torque-measuring device or gauge to verify that the final torque matches the specification, ensuring the wheel studs aren’t over- or under-tightened. The other tools don’t provide the same balance of high-torque capability and measurable control. A torque wrench by itself sets and reads a specific torque value but doesn’t inherently amplify your effort. A torque stick gives a rough, preset limit and isn’t as precise for final torque. An impact driver delivers fast torque without guaranteeing an exact torque reading, which risks under- or over-tightening.
