The installation of Torque-Tight lug nut indicators is a rather simple process. With the proper tools and a few minutes of your time, you will be up and running a safer rig!  



Step 1: Torque lug nuts to specified FT/LBS. Be sure to use a high quality torque wrench, and remember; you must release the pressure in your torque wrench to maintain proper calibration.


Step 2: Place your Torque-Tight™ lug nut indicator facing the next nut. You always want the indicator to rotate to the outside rather than in, this allows for a larger visual pattern should a lug nut come loose. Remember; Lefty Loosey, Righty Tighty.


Step 3: Press the indicator on the nut, and rest assured that you now have a great visual aid for your walk-around.

 TIP: Using a socket to press the lug nut indicator on is much easier on your fingers.  


How to Measure for Torque-Tight

Proper measuring techniques are very important in order for your Torque-Tight to fit properly. The easiest way to do this is to utilize a high quality 6 point Socket Wrench, however, there are some things to keep in mind.

First, when sizing up a nut, always remember that metric and standard (inch) nuts may be used. With that in mind, be sure to check that you are using the proper size, for example, when you are working with large nuts, a 1-5/16” socket will fit and work okay on a 32mm nut… but a 32mm will fit properly. Always try to size up nuts to the smallest size socket that will fit.

Second, if nuts have been replaced over time, be sure to check multiple nuts throughout your truck(s). The ASME B18.2.2 Spec for Heavy Hex nuts allows for a large variation for the Min-Max of the “across the flats” dimension. Be sure that your nuts are all commonly sized!  

If you do not have a socket large enough, simply use a pair of calipers to measure across the flats of the nut, as seen in this image.
