Is It Necessary to Maintain A Torque Wrench?
As you use it for a very specified amount of torque, a precise wrench is crucial. A torque wrench is a very sensitive tool. So, without maintaining it properly, it can break at any time.
Also, keep a paid-off snap-on toolbox if you like to repair mechanical items by yourself. It will save you time and the hassle of looking for tools while working.
Here are some tips. If you can remember these tips, then you’ll surely see the difference in the long run. So, let’s check out 5 tips to maintain your torque wrenches-
Tip 1: Always reset the dial after every use.
Tip 2: You can use a ratchet. It will allow you to perform counterclockwise torque beside clockwise. Additionally, a Ratchet with a lesser tooth count will allow the torque limit to go higher. For different applications, you will find different wrench sockets and ratchets.
Here are some good-quality ratchets recommended for you-
- In our opinion, DURATECH 3-Piece Ratchet Set is probably the balanced choice for anyone. It’s neither cheap nor too expensive and offers great service.
- EPAuto 1/4” & 3/8” Drive Socket Set offers two different drive sizes in one. And the whole toolbox comes with 69 pieces.
Tip 3: As a sensitive tool, a torque wrench can easily break if the nut or bolt is rusty. Always clean the dust and grime off nuts and bolts before using the torque wrench.
Tip 4: Calibrate The Wrench Yearly.
Tip 5: Never put an extension to the torque wrench handle.
Frequently Asked Questions (FAQs):
Can You Use A Torque Wrench To Loosen Bolts?
You can’t loosen a bolt by using the torque wrench. It is precisely made for tightening the bolts. So, don’t use it for loosening. Otherwise, this sensitive tool will break. Besides, for loosening, you don’t need a torque wrench. A regular wrench is fine.
When Should I Use a Torque Wrench?
A torque wrench is used in repairing heavy mechanical items, such as cars. While changing a car tire, the bolt needs to be tightened with precise torque. In these cases, if regular wrenches or pliers don’t work, you will need a torque wrench.
What Can I Use Instead Of A Torque Wrench?
For specific tightening requirements, a torque wrench is the only option. For example, if the lug nuts on a car wheel are not tightened appropriately, accidents can happen. But where you do not need precise tightening, you can use a regular wrench or pliers.
How Much Are Torque Wrenches Worth?
As a precise and delicate tool, torque wrenches are a bit expensive. You can find a torque wrench for between $50 – $200. It depends on the size and quality. Expensive ones have more torque limits. But the expensive torque wrench will serve you longer and you will get more torque limit.
