The torque requirements of bolts and nuts depend on the specific application scenario and material, size and other factors. Torque is expressed by the moment (force multiplied by the length of the lever), which is the rotational force applied to the screw. The correct torque ensures that the connector is tight to the design requirements, avoiding problems caused by too tight or too loose. To use a torque wrench properly, here are some basic steps: Select the right torque value: Adjust the torque setting on the torque wrench according to the desired torque requirements. Ensure that the selected torque value matches the specifications and requirements of the connector. You can refer to the product manual, design drawings or standards provided by the manufacturer. Calibrate the torque wrench: Periodically calibrate the torque wrench to ensure accuracy and reliability. Calibration can be performed by specialized test equipment or mechanisms, or by self-calibrating according to the instructions for the use of the torque wrench. Ensure proper wrench grip: The torque wrench is held correctly to avoid interference with the measured value and to provide stable application. Make sure to hold the handle part of the wrench and not touch the torque adjustment part of the wrench. Applicable rotation force: Insert the torque wrench into the threaded hole of the bolt or nut and apply the rotation force to bring the connector to the desired torque value. The rotation process should be smooth and even to avoid sudden application of force or use of excessive force. Stop when the torque is reached: when the wrench emits a “clamp” sound or the indicator indicates that the set torque value is reached, the force is immediately stopped. Do not continue to apply force to prevent exceeding the design specification. Record torque values: Information about applied torque values and connectors should be retained for future reference and tracking. Keep in mind that each bolt and nut connection may have different torque requirements, so be sure to follow professional specifications and recommendations, such as product manuals, design drawings or manufacturer standards, and ensure that the tools used are properly operated and maintained.
