Which of the following is not a basic rule to follow when using a torque wrench?

• A. Avoid using swivel joints
• B. Pull only on the wrench handle
• C. Clean fastener threads
• D. Use short, jerky pull motions for accuracy

Answer: (D)

Using a torque wrench effectively is critical for ensuring that fasteners are tightened to the correct specifications, which helps maintain the integrity of mechanical connections. The option that emphasizes using short, jerky pull motions for accuracy is not a basic rule to follow when using a torque wrench because it can lead to inaccurate torque readings and can potentially damage the wrench or the fastener. When you apply a steady, controlled pull on the wrench, it allows for better measurement of torque and improves the accuracy of the fastener tightening. In contrast, short, jerky motions can create variations in torque application, making it difficult to achieve the desired specification. Therefore, maintaining a smooth and continuous pull is essential for proper torque application. Other rules, such as avoiding swivel joints or ensuring the cleanliness of fastener threads, are integral to achieving accurate and reliable results when using a torque wrench.
