9 Things You Should Know About Your Torque Wrench

And as we’ve argued here before, your torque wrench is an investment as well, not just a purchase. Here are nine things you should know about caring for it.

1. One click is enough

When you’re tightening a bolt, one click is enough. Many users allow their wrenches to click more than once, but this means they’re applying added torque to the bolts. Use your tool in a smooth, steady fashion and let it click just once.

2. Be careful with “crow’s foot” fittings

Torque wrench square drives CAN be fitted with “crow’s foot” style fittings. However, these fittings can alter the torque of the tools. If you do use a crow’s foot, it’s important to find the right offset to apply to the set torque.

3. Use the adjustment lock

If your torque wrench comes with an adjustment lock, be sure to apply it before operating the tool. It’s easy to accidentally adjust the settings on your wrench while you’re using it, leading to unwanted – and unintended — changes.

4. Don’t make your own “extensions”

When working with your torque wrench, avoid using pipes or other objects to extend the wrench handle. Not only is this practice dangerous, it can also damage the tool and throw off its accuracy.

5. Use caution when loosening

Torque tools are designed to make things tighter, but some can also work to loosen bolts. But if the bolt can’t come loose within the wrench’s maximum torque, you should use another tool.  Exceeding that maximum can affect the wrench’s accuracy.

6. Follow the marked points

Most wrenches come with a marked loading point on their handles, but not everyone uses this guide. But the loading point is there to help you. Keep your hand centered above it as you work to achieve accurate results. The loading point is also important when calibrating your torque tool.

7. Follow the required torque when adjusting your wrench

Your wrench’s manufacturer should have provided the required torque for your equipment. When adjusting your torque wrench, make sure those levels are met to ensure an accurate setting.

8. Make sure it can go counterclockwise

Many torque tools only turn in a clockwise manner. You should always check your wrench’s specifications before you try to turn it counterclockwise. If the tool isn’t designed to work that way, turning it in the wrong direction can lead to a loss of torque control.

9. Wind your wrench back when storing it

When we say “storing it,” we don’t mean “putting it away for the night.” We’re talking about a torque wrench that you may only use occasionally. If you let the wrench sit for a long time without winding it back, the wrench will weaken and become inaccurate over time.
