Before using a torque wrench you must ensure that the wrench has been what?

• A. Cleaned and polished
• B. Calibrated and label affixed
• C. Repaired and inspected
• D. Lubricated and oiled

Answer: (B)

Ensuring that a torque wrench is calibrated and has a label affixed is essential for accurate and reliable measurements. Calibration verifies that the torque wrench provides precise torque settings according to the manufacturer's specifications. This process often involves comparing the wrench's readings to a known standard and adjusting it if necessary. The label serves as an important reminder of the calibration date and any required maintenance, helping prevent the use of an uncalibrated tool, which could lead to pneumatic or mechanical failure due to improper torque application. Using a torque wrench that has not been properly calibrated can result in over-tightening or under-tightening of bolts and nuts, potentially leading to equipment failure or safety hazards. Therefore, proper calibration and the application of a label are critical steps to ensure that the tool meets the required standards for accuracy and reliability in mechanical tasks.
