How To Set Torque Wrench Inch Pounds

Now that we know how important a torque wrench is, it is important that you know how to set it right for proper use.

When buying a torque wrench, you may get that its measurements are either in inch-pounds or foot-pounds. In case the torque wrench has the foot-pounds scale, you may have to convert the inch-pounds to foot-pounds.

The general rule for conversion is that 1 foot is equal to 12 inches. The same applies to the opposite of the conversion.

A good example is when you want to use a torque of 30-foot pounds, then multiply the value with 12 to get 360-inch pounds as the correct torque to use. Simply divide by 12 if it is the opposite.

A dual-range torque wrench will have both the in.-lb and Nm scales on the opposite sides of the wrench handle. You need to know how best to read them before using the torque wrench.

Each torque wrench will have the main scale found on the handle body and a micrometer scale on the knurled handle. The main scale will be for coarse adjustment while the micrometer scale is for fine adjustment.

To set the torque on the wrench, start with the coarse-scale adjustment. This is done by depressing the torque wrench collar and holding it down as you turn the knurled handle until it reaches the desired torque on the main scale. The micrometer scale should be on the zero mark before find adjustments are done.

Now it is time for fine adjustment. This time we use the micrometer scale. You will notice each division is 1inch-pound. So, to get an additional 5 inch-pound, simply turn the micrometer scale handle until the mark is on 5.

Now that you have set the torque, release its color to lock in your torque setting.
