- Step 1: 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.
- Step 2: Check the manufacturer specifications and determine the correct torque settings for the bolt you are tightening.
- Step 3: Fit the ratchet head to the bolt.
- Step 4: Apply pressure to the handle of the wrench. Your arm should form a 90 degree angle to the wrench.
- TIP: Most torque wrenches are held in the center of the handle, but some wrenches have a line indicating where the hand should be placed.
- Step 5: Tighten the bolt until the torque wrench indicates that the desired torque has been reached.
- TIP: Don't jerk the wrench -- apply force in a smooth motion.
- Step 6: Have your torque wrench properly calibrated after frequent use as it is a sensitive tool.
- FACT: Archimedes discovered the concept of torque.
