Automotive torque wrenches are one of the most common and useful tools in the modern workshop, and are used for a wide variety of roles. When used in the workshop, you will be able to get accurate and reliable results for a job.

Essentially, an automotive torque wrench is used to tighten nuts and bolts to a predetermined level of tightness. The wrench is set up prior to use so that when a particular pressure is reached it will no longer tighten the bolt any further. There are a large number of jobs to carry out on a car or truck engine that require a bolt to be tightened to a specific level, and all of these jobs require a torque wrench in order to carry them out properly.

The advantages of being able to tighten a nut to a predetermined level are related to the levels of precision with which a modern engine needs to be maintained. In order to ensure a long life for all components within a vehicle, it is necessary to fasten them into place in a way that minimizes stresses on them and the items that they are connected to. Vibration is minimized by tightness, however over tightening bolts will place a large load on the bolt and surrounding area that can cause failure. By specifying a particular load on the bolt, they can be tightened to the exact level needed, and this in turn will protect the system.

The Automotive torque wrench is essentially an adjustable tool that you can set up to an exact level and then use as required. They come in a number of different designs to suit your purposes; however typically, they will be a lever that connects to a socket. This can rotate freely when required or be fixed into place. As a bolt tightens, the amount of load that it places on the wrench increases, the wrench can be set up to release at a particular level of pressure so that as soon as the load on the bolt approaches a certain level – for example 10Nm , the wrench will not tighten the bolt any further.

Red Hill Supply offer an extensive range of different automotive torque wrenches that are designed to carry out a full range of different jobs in the workshop so that you can confidently perform maintenance to the highest possible standards without worrying about errors due to over tightening that could cause long term damage to parts of the engine or other systems. It is always important to have a tool that is specially designed for the task at hand, and this means that you will often require a smaller or larger wrench depending on the size of the bolt and the precision required in order to get the task done properly.

A standard split beam automotive torque wrench such as those made by Precision Instruments is intended to offer mechanics the flexibility and power required to carry out a large number of high pressure jobs on a vehicle and is available from around $438.67. These larger wrenches, which measure around 48” in length are designed to work from around 2-600ft/lbs, and allow you to apply exactly the right amount of force to a bolt relatively simple thanks to the length of the bar.

Smaller wrenches such as the SK Hand Tools SKT74016 are designed to offer precise tightening of bolts to lower pressures of between 30-200ft/lbs. Smaller at 19.25” in length, these lighter automotive torque wrenches are designed for accuracy and reliability in use, and are ideal for smaller jobs thanks to their ¼” bit.

No matter what kind of automotive torque wrench that you buy, it is important that it comes with a calibration certificate. This will prove that the measurements and settings on the wrench are completely accurate and that you can rely on it to perform properly when it is needed.
