What is a torque wrench?
A torque wrench is a socket wrench handle that indicates the torque applied to the socket when the wrench handle is rotated. Types of Torque Wrenches There are two types of torque wrenches. The exposed pointer type has a long pin that remains straight as the handle flexes under torque load. An arc-shaped scale on the handle moves under the pointer and allows a direct reading of the torque as indicated by the pointer. The clicker type has an enclosed mechanism. These wrenches have a micrometer-type adjustment on the end of the handle where you can set the desired torque. When the desired torque level is reached, an audible “click” is heard – and felt. The clicker type is more common and somewhat easier to use – especially when the top of wrench is not readily visible. On the other hand, the clicker type only tells you when you reach the preset torque; it does not allow you to measure torque. The clicker type torque wrench normally has a ratchet head, but the exposed pointer top does not
A torque wrench is a tool that allows one to control circular force, or torque, when putting in, removing or tightening a bolt or a nut. The torque wrench comes in many different styles and levels of complexity depending upon its applications. A simple torque wrench, called a beam torque wrench, has a scale on the wrench, which will measure the amount of torque being used. The scale is attached to a slightly flexible arm that will show the scale of torque when the torque wrench is in use. This type of torque wrench may be okay for general use, but it tends to be somewhat inaccurate in its measurements. When one must very specifically measure the amount of torque, using the simple torque wrench is inadvisable. Another type of torque wrench in quite common use is called a click torque wrench. Prior to using the wrench, one can set the wrench to provide a specific amount of torque and no more. When the amount of torque needed is reached, the torque wrench mechanism slips so that no more f
