How To Use Torque Wrench: What Is It, How It Work, Ways To Use

What is a Torque Wrench and How Does it Work

A torque wrench is a tool used to apply a specific amount of torque to a fastener, such as a nut or a bolt. This could otherwise prevent problems such as a stripped bolt or having to resort to using a stripped lug nut remover and using an Easy Out. It is designed to ensure that the correct amount of force is applied during assembly and maintenance operations.

The tool works by measuring the amount of rotational force (torque) applied to the fastener and alerting the user when it reaches the desired level.

  • The most common type of torque wrench is an adjustable click-type wrench, which has an adjustable handle that can be set to a specific torque value. When this value is reached, an audible click will sound, indicating that enough force has been applied. This type of wrench also features a locking mechanism that prevents further tightening once the desired level has been reached.
  • Other types of torque wrenches include beam-style wrenches, dial-indicating wrenches, and digital wrenches. Beam-style wrenches feature two arms connected by a beam; when enough force has been applied, one arm will move up while the other moves down in order to indicate that enough force has been achieved.
  • Dial-indicating wrenches feature an analog dial with markings for different levels of torque; when enough force has been achieved, it will be indicated on this dial. Digital wrenches are similar but use digital displays instead of analog ones in order to indicate when sufficient force has been achieved.
  • Torque wrenches are essential tools for any mechanic or engineer who needs precise control over how much rotational force they apply during assembly or maintenance operations; they help ensure that parts are not over-tightened or under tightened which can lead to damage or failure down the line if not done correctly.
