Features of Electric Torque Wrench

Efficient and fast: The electric drive enables the electric torque wrench to complete tasks quickly when tightening and loosening bolts, improving work efficiency.

Precise control: The built-in torque sensor can accurately measure the torque value to achieve precise torque control, avoiding the risk of over-tightening and loosening of bolts.

Automatic stop: The electric torque wrench will automatically stop outputting torque after reaching the preset torque, avoiding human judgment and operation errors.

Wide range of applications: The electric torque wrench is suitable for bolts and nuts of different specifications and sizes, and can be flexibly used in various mechanical engineering scenarios.

Improved Safety: Precise torque control and automatic stop function help prevent bolt breakage, loosening, and work accidents, improving work safety.

Data recording and tracking: The electric torque wrench is equipped with a data recording function, which can record the torque value and tightening process, and can be connected to a computer via WIFI or Bluetooth.

Lightweight and Portable: Some electric torque wrenches are designed with a lightweight design, which is easy to carry and move, and is suitable for on-site operations.

Precautions For the Use of Electric Torque Wrench

The fastening of high-strength bolts should be carried out at least twice. The first time is the initial tightening. The minimum torque value of the initial tightening is not less than 40% of the torque value required for tightening. The second time is the final tightening. To make all the bolts in the bolt group evenly stressed, the initial tightening and final tightening should be performed in strict accordance with the tightening sequence. Operate symmetrically according to the “double-cross” shape.

Operate in strict accordance with the operating procedures of the electric torque wrench. The bolts that are initially screwed should be marked for confirmation to prevent bolts from being skipped. When installing the bolts, ensure that the friction surface is in a dry state, and the final tightening torque must be carried out according to the requirements of the set value.

Due to the influence of external force, temperature change, vibration, and other factors on the torque or pre-tightening force of the bolt, the final torque value produced each time is different, and the torque deviation is normal within ±5%.

The electric wrench whose torque has been set can be rotated 30° from the pre-tightening of the bolt to the tightening. For the bolts that have reached the set torque, there is no need to use the wrench again, otherwise, the bolt torque will be increased, and the load of the bolt and the electric wrench will also increase, which will damage the bolt and the wrench.

Clean and replace grease regularly. Generally, after working 5000 times, it should be cleaned and refueled to prolong the service life.

FAQ

Q: What are the rules for torque wrenches?

A: Stop applying pressure immediately when the desired torque is reached to avoid overtightening the fastener. Once you stop applying pressure, the wrench will reset, allowing you to use it to tighten the next fastener to the same torque. At lower torque settings, the click will be less noticeable than at higher torques.

Q: Is it OK to max out a torque wrench?

A: However, exceeding the maximum torque rating that the wrench can handle (except for the digital type) can affect the wrench calibration or damage the tool itself. This is more likely to happen when loosening a tight bolt; hence most manufacturers will recommend using it for tightening applications only.

Q: How accurate are electric torque wrenches?

A: Every torque wrench operates within a given accuracy range, such as ±2-4% over 20% to 100% of full-scale.

Q: How to calibrate an electric torque wrench?

A: To calibrate an electric torque wrench, you typically need to compare it to a known standard. This involves applying a known torque load to the wrench and comparing the wrench's reading to the standard. For DIY calibration, you can use weights and a calibrated arm. Some wrenches also have built-in calibration features that can be accessed through a button sequence.

Q: What is the tolerance on an electronic torque wrench?

A: The permissible deviation from the set value depends upon the specific tool type but is either +/- 4% or +/- 6% depending upon the type of tool used. When tested to the standard, the force needs to be applied to the torque tool within +/-10 degrees of a right angle to the longitudinal axis of the tool.
