If an ordinary socket wrench doesn't meet your preferences, you can step up to and including hydraulic torque wrench, or an electrical torque wrench. Both of these are made by Hytorc wrench, a very reputed manufacturer. They are the ones that I have already been using for years, but I'm likely to generalize and speak as to the every type one of these power tools is for.
First I will begin with the basics. A hydraulic torque is made to exert torque on some type of fastener. The goal can be to quickly and securely fasten or loosen various nuts. They apply an amount of torque to a lubricated fastener beyond what a human could muster, usually in conjunction with an effect socket. These were first introduced in the 1960's, but have evolved considerably after that as a result of manufacturers constantly updating and advancing their designs. This has result in the present day hydraulic torque wrench, one which is light as a result of exotic alloys, having an inferior nose radius to increase how many spaces it'll squeeze into, possessing multi-position reaction members, and you may also now run multiple tools off of 1 power pack simultaneously. Today's modern torque wrenches are optimized for efficiency and flexibility in their uses.

What makes a hydraulic torque wrench work is that it generates torque using only hydraulic means, it is self ratcheting, and it will need to have an exact solution to measure the total amount of torque applied to the fastener. A holding pawl design is popular amongst most manufacturers to lock the wrench in position, but each involve some declare that there design is superior. I say whichever one works, works. These wrenches routinely have an accuracy rating of +/- 3%, with a higher repeatability rate. This makes them suited to large bolts that want a higher level of accuracy. The greatest advantageous asset of a hydraulic wrench doesn't have anything regarding performance, but with people who utilize them - these torque wrenches are significantly quieter than similar output pneumatic impact wrenches. That is good results that you can't measure in strength, repeatability, or work output increases - it is about the health of people who use it.
A power torque wrench is a gearbox that's linked to an electrical motor. This gearbox was created in this way that it absorbs the torque, allowing the consumer to work the wrench with minimal effort. They are typically used if you have no need for torque strength accuracy being used on the nut or bolt, or whenever a very stubborn nut needs to be removed. The gearboxes can be of ratios as high as 4000:1. and this is adjusted by controlling the voltage. Due to the fact it is powered by electricity, you can find waterproof models for when water is a concern on the jobsite. It's often confused with an impact wrench due to its similar design, however it is actually a many different tool, and is even more distinctive from a hydraulic torque wrench. All of it comes down seriously to the task and getting the best tool for it.
Different Types Of Torque Wrenches
So you're trying to find out more about different types of tools and you've recently read about torque wrenches and are interested in studying different types?
You've arrive at the best place!
As you probably know if you are reading this information, a torque wrench is a type of wrench designed to utilize torque (force around an axis) to a bolt or nut. Torque wrenches are distinguished from other types of wrenches because they can measure and/or control the total amount of force that's applied allowing the correct total be utilized and ensuring that the bolt or nut is neither too loose nor too tight.
Let's start with the most simple designs and workout way up.
A simple torque wrench is usually merely a long wrench with an analog needle on it. Once the wrench tightens a bolt, the needle will move and point out the value representing the total amount of force being used (for example, 50 pounds of force). These will occasionally have to be calibrated, and because the needle is frequently exposed it may be bent or moved accidentally and no further point out the right value.
There are also electronic torque wrenches that work basically exactly the same, except rather than an analog gauge they've an electronic digital display. The bonus to this is that it can be easier to see because the value is shown in numbers in addition to being easier to see with less light (assuming it is bright or runs on the backlit display) such as if you're working behind a big bit of machinery that's blocking the light.
There are torque wrenches that may be set to a particular amount of force which will stop applying force once that level is reached to simply help prevent over-tightening. With this type you don't have to concentrate the maximum amount of on the gauge because it'll stop tightening at the right force.
Hydraulic torque wrenches use hydraulics to tighten or loosen an enthusiast or bolt. This kind of wrench runs on the predetermined amount of torque and can operate more quietly than similar pneumatic wrenches, not forgetting many individuals feel hydraulic wrenches are a better choice due to the precise nature associated with tightening bolts.
What Are Torque Wrenches? What Do They Do?
If you've ever loosened lug nuts on car to take the wheels off or tightened them after putting the wheels on, you've probably used a torque wrench. Well, i'd like to rephrase; if you've ever put the lug nuts back on an automobile, hopefully you used a torque wrench.
A torque wrench is a wrench designed to let you tighten nuts or bolts without over-tightening them, which is prevented in a variety of ways.
Lets get back to the lug nuts. If the lug nuts on your vehicle have to be tightened to 75 foot pounds you'll need to make sure you have a way of knowing when you've reached 75 foot pounds. Are you just going to use a regular wrench and guess?
That's why I said above that "hopefully" you used a torque wrench. A typical torque wrench may have a measure on it that teaches you just how much force you are applying. As you tighten the nuts the needle will point out the total amount of force being used which will permit you to apply the right amount.
Most wrenches of this type are fairly long to allow sufficient leverage to generate enough force. If you're tightening your lug nuts with a 16" wrench you're going to have a much simpler time than if you test it with a 10" wrench, for example.
Although some types of these wrenches just have a measure to inform you just how much force you're applying, others already have mechanisms that stop you from applying a lot of force. For example, some wrenches have a clutch that disengages when the right amount of force is applied so you cannot tighten the bolt any further.
Now, what if you're working together with bolts that are bigger compared to the lug nuts that hold your wheels on? What if you want to tighten something to 10,000 feet pounds rather than 100? In these cases there's another type of wrench, a hydraulic torque wrench, that uses hydraulic power to utilize the required force to the bolts. Hydraulic torque wrenches have been with us because the mid-60's but recent improvements in their design have made them smaller, lighter, and and more easily able to suit into tight spaces. This sort is recognized as a lot better than pneumatic wrenches since they are quieter, lighter, and more accurate.
How A Pneumatic Impact Wrench Works
A pneumatic impact wrench or air gun is a very helpful tool for removing stubborn nuts and bolts. It runs on the strong jerking motion to simply help free fasteners which were over tightened or which have rusted over time. Compared to a traditional wrench, this can be a real improvement, and could make difficult jobs far easier. There is a wide selection of different types of impact wrench on the market, pneumatic being one of them. In this information, we shall consider the alternatives and their relative merits in addition to explain the function of the impactor generally.
How an Air Gun Works
An air gun differs from other powered wrenches in that it delivers its torque in instantaneous jolts as opposed to with a steady force. Essentially, the internal motor spins a spinning mass, which then hits the output shaft. This repetitive impact results in the rattling noise and also in the potency of the wrench. The numerous minor impacts work to reduce the torque felt by the consumer while greatly increasing the instantaneous torque applied to the nut or bolt. Multiple short, sharp applications of torque can remove even probably the most stubborn fastener, even one that has rusted severely. Models typically differ in both their torque and their weight, each of which make an impact to the tool's usability.
Different Varieties
A pneumatic impact wrench has several competitors in the proper execution of different drive mechanisms. Hydraulic impact wrenches are used in some industrial applications where pressured hydraulics are available, but electric impact wrenches are very popular among home users. It's even possible to have cordless electric variants, although they are typically down on power compared for their more heavy-duty brethren. The kind chosen is determined by the context and circumstances; a hobbyist who requires a portable powered wrench will likely prefer a cordless electric version, while more severe professional use will likely require the more powerful pneumatic option.
Conclusion
A pneumatic impact wrench is a good selection for removing difficult nuts or bolts. There are several alternatives, such as the cordless electric variant, that might work better for a few people, but also for sheer power and performance, it is hard to beat compressed air. Turn to the torque and weight of the air gun to determine its suitability. There is no sense in buying a wrench with either much less or vastly greater torque than you require, and much model can cause you some discomfort when used for long periods.
