Always dial the wrench back to zero (never below zero) when you’re done with it.

What should a torque wrench be set at?

In the stationary position, the wrench should read 0. Turn the wrench around a nut or bolt and look at the arrow. As you turn the wrench around a nut or bolt, the arrow will move and represent the amount of torque you’re applying. For example, if you turn the wrench around the nut and it reads 30 lbs.

What are the general rules of using torque wrenches?

-Always pull, DO NOT PUSH, to apply torque and adjust your stance to prevent a fall. -Do not use with sockets or fasteners showing wear or cracks. -Ratchet mechanism may slip or break if dirty, mismatched or worn parts are used, therefore, properly inspect your torque wrench before using.

How do you use a torque wrench step by step?

To use a torque wrench, adjust the handle and set it to a specific level of torque. Use the tightener on the end of the handle to lock it in place.

How is a torque wrench calibrated?

To obtain the correct setting for your torque wrench, you will need to multiply the distance from step one by whatever weight you will be using to get the inch-pounds. (For this example, we will use a 20-pound weight.) Then divide that number by 12, which will give you the foot-pounds.

How often should I calibrate my torque wrench?

every 12 months
In short, it’s standard practice to calibrate your torque wrench every 5,000 cycles or every 12 months, whichever comes first.

How does a torque wrench measure torque?

When the wrench is used to apply torque, the lever bends and the indicating beam stays straight. Thus, the end of the indicating beam points to the magnitude of the torque that is currently being applied. This type of wrench is simple, inherently accurate, and inexpensive.

How do you properly use a torque wrench?

What is a torque wrench and how do you use it?

A torque wrench is used where the tightness of screws and bolts is crucial. It allows the operator to set the torque applied to the fastener so it can be matched to the specifications for a particular application. This permits proper tension and loading of all parts. A torque wrench uses torque as a proxy for bolt tension.
