A torque wrench is a tool that must be in every mechanic’s tool set. These kinds of wrenches can give you the ability to tighten bolds and nuts to the recommended feet per pounds settings without worrying about over-tightening and possibly stripping of the nut, or worse, damage your engine.
What is a Torque
In simple terms, torque refers to tightening force. Safety critical automotive parts always have certain manufacturer’s torque settings stating the amount of torque that’s needed for their fasteners.
Utilizing too much force can result in damage to the fastener or damage to the mating parts. Similarly to that, use too little torque implies giving a bolt the opportunity to back out or shear off when the bolted joints are loaded, yielding in a potentially dangerous failure.

Because of that, it is really crucial to guarantee that you are using a torque wrench to apply the right amount of torque when the job calls for it.
On the other hand, a torque wrench is a kind of wrench that lets you precisely tighten a fastener to a torque they specify. Normally, you use one wrench and swap out sockets to match your bolt size, similar to how you’d use a ratcheting socket wrench.
These wrenches comes in many different versions, nonetheless those versions used in the automotive industry are the most common ones.

When your fastener is correctly torqued, it can stay tight no matter how much vibration is present while the vehicle is in operation. If the bolts and nuts are improperly torqued, that could present disaster for you as well as your vehicle.
How Do They Work
Most torque wrenches you find today are going to have a ratchet mechanism that’s going to let you keep the wrench on the bolt or nut once it reached the end of the rotation.
In other words, you don’t need to take the wrench off the bolt in order to do another rotation. All you need to do is just turn the torque wrench in the opposite direction and start all over again.
Its ratcheting mechanism utilizes gears inside the head of the torque wrench. These gears lets the handle to rotate backward while the fastener you are working with stays still and precludes it from unloosening. Due to this fact, you can work much faster in tight spaces.
