With all the brands and models out there, how are you supposed to identify and buy a torque wrench for your needs? This process gets doubly hard if you’re a beginner, not only do you have to look at the price of the torque wrench, you also have to check for durability, quality, features and usability. There are a few tips available online on sites like http://toptorquewrench.com/. To make this process simpler for you, we’ve written a short and simple how-to guide to help you find the perfect torque wrench that suits all your needs.
What is a torque wrench?
Basically, it’s a wrench that allows you to control the amount of torque (or force) you’re using when you’re unscrewing or tightening a bolt. Most torque wrenches have a built in gauge for you to see exactly how much torque you’re using.
What are the different sizes of a torque wrench?
There are 3 main sizes, and each size is designed for a specific type of use.
The small size typically has a torque of 30-200 in. lbs. This is pretty low, so this torque wrench is ideal for transmission servicing. The next size, medium, has a torque of 20 – 30 ft. lbs. However, some medium-sized torques can even go up to 250 ft. lbs. Medium torque wrenches are best used for engine rebuilding and reconditioning. Large torque wrenches have a torque capacity of 1000 ft. lbs., making them ideal for heavy automotive or industrial use.
What are the types of torque wrenches?
1. Deflecting Beam Torque Wrench
This wrench applies torque to a deflecting beam instead of the usual coil spring, increasing its durability. It also has a built in indicator to let you know when your desired torque has been reached. The only downside to this torque wrench is that it is unidirectional. However, it can easily be modified with a torque angle adaptor to overcome this problem.
2. Micrometer Torque Wrench
This torque wrench is extremely easy to use – all you have to do is twist the handle to set it to your desired torque setting. When applied to a nut/bolt, there will be a “click” sound when the set torque is reached. The torque will reset after each use.However, this torque wrench requires frequent recalibration.
3. Dial-Type Torque Wrenches
These are the most accurate torque wrenches on the market. However, they are slightly more expensive and take a little getting used to as they are wider than regular torque wrenches.
4. Electronic Torque Wrenches
These torque wrenches have an LED screen for you to set and read the torque value. With some models, you can even save previous torque values for record-keeping purposes!
5. Torque-angle Torque Wrenches
These torque wrenches measure angle of rotation in addition to torque, improving accuracy and efficiency. These wrenches also come with a LED screen for you to program your angle and torque into.
6. Interchangeable Head Torque Wrenches
As the name indicates, these torque wrenches have interchangeable heads of various sizes. This truly gives you value for money, as you can use one wrench for a variety of purposes.
As you can see, there are several sizes and types of torque wrenches out there. Each kind has it’s own pros and cons, so make sure you accurately identify what exactly you require the wrench for. Remember, when it comes to torque wrenches, it’s worth paying for quality.
