Many of us know what a torque wrench is but few know how to use a torque wrench correctly. Torque wrenches have similarities to a socket wrench, but other than the ratcheting action and the ability to change the direction you want to go, torque wrenches are on a level of their own.

A torque wrench is by definition, a precise measuring device, and we are told to treat it like it is fragile. Torque wrenches are not necessarily fragile but they can be damaged very easily so DO NOT drop it. Ill get more into that in a bit.

The basics on how to use a torque wrench are as follows.

First and foremost you are going to need to find the right socket for the nut or bolt you are working on. Without having the proper size you will have problems for the get go. If your socket is to loose you will not be able to get a proper reading due to the movement and the possible added leverage from the socket. Place socket on wrench and get ready for the fun part...:)

Next you will need to set the torque you will be using on the specific nut or bolt. Pretty much all nuts and bolts will have a different torque spec so you will have to check with the manufacturer. On the bottom of your typical click-type torque wrench there will be some sort of lock. This is to prevent the torque setting from moving while you are working. It will be a slid-able ring or a twist-able knob. You must loosen this before you can set it. Once you find your spec you will see the numbers and be able to match them on your wrench. Once torque setting is in place lock it in.

Now you are ready to torque down some bolts! Before you do, remember with the click-type torque wrench once you here the click STOP. Continuing to tighten will tighten nut or bolt to much and be "out of spec".

As I said earlier DO NOT drop your torque wrench, use it for a hammer, (Ya i know you have), or throw it around. Inside your wrench there is sensitive pieces and grease that makes your wrench work. Without it you will not be putting the right amount of torque needed for the object you are working on. Any one that owns one should have their torque wrench calibrated or adjusted once or twice a year. If you use it a lot then you would want to do it sooner and more frequently. Torque wrenches are a necessity for any auto mechanic.
