With a torque wrench, you can set a bolt to the proper tightness and cut down on wear and tear.
You Will Need
* 1 A torque wrench
* A loose bolt
* A ratchet head
Identify the type of torque wrench you have. Each type has a different means of displaying torque, or twisting force. Beam, dial, and digital wrenches have a scale or indicator. A clicker torque wrench clicks when the desired torque is reached.
Check the manufacturer specifications and determine the correct torque settings for the bolt you are tightening.
Fit the ratchet head to the bolt.
Apply pressure to the handle of the wrench. Your arm should form a 90 degree angle to the wrench.
Most torque wrenches are held in the center of the handle, but some wrenches have a line indicating where the hand should be placed.
Tighten the bolt until the torque wrench indicates that the desired torque has been reached.
Don't jerk the wrench – apply force in a smooth motion.
Have your torque wrench properly calibrated after frequent use as it is a sensitive tool.
Fact: Archimedes discovered the concept of torque.
