How to Use a Click Type Torque Wrench
Torque ensures that a fastener properly holds a given part in place. Without a torque wrench, you have no knowledge of the exact amount of force you apply to the fastener. Click style torque wrenches signal that you have reached the proper torque by emitting a click sound when you reach the desired torque setting. To ensure that a torque wrench is giving an accurate torque reading, you need to have the wrench calibrated by a professional annually. Also take the wrench to be evaluated if it receives a sharp blow from falling.

Instructions
1. Read the torque specification to locate the torque setting for the fastener you need to tighten.
2. Set the torque setting on the torque wrench. Turn the roll dial located on the torque wrench to the specified torque setting you found in step 1.
3. Thread the fastener into the threaded hole by hand.
4. Attach the socket to the torque wrench.
5. Place the socket onto the head of the fastener. Slowly turn the torque wrench to tighten the fastener. The tighter the fastener becomes, the slower you need to turn the torque wrench. Listen for the click sound to emit from the torque wrench. The click will not generally be loud, and you will feel the click more than hear it.
6. Stop tightening the fastener when you click. Do not tighten the fastener past the click, or the fastener will not have the proper torque setting
