Which of the following statements is true about micrometer torque wrenches?

• A. It uses a micrometer adjuster to set torque
• B. It relies on a digital display
• C. It uses a dial gauge
• D. It uses a fixed setting

Answer: (A)

Setting torque on a micrometer torque wrench is done with a micrometer-style adjuster. You rotate the micrometer thimble to move the spindle and set the desired torque value on the scale along the sleeve, giving you precise, repeatable control in small increments. When you apply the fastener, the wrench delivers the set torque and usually provides a tactile or audible indication as soon as that value is reached. This type relies on the micrometer mechanism rather than a digital display or a dial gauge, and it isn’t fixed at one setting—you can adjust it to different values as needed.
