If a regular socket wrench doesn't meet your requirements, you are able to step up to hydraulic torque wrench, or a power torque wrench. These two are created by Hytorc wrench, a very reputed manufacturer. They're those that I have been using for a long time, but I'm going to generalize and speak as to the each kind one of these simple power tools is for.
First I will begin with the basics. A hydraulic torque is made to exert torque on some kind of fastener. The goal may be to quickly and securely fasten or loosen various nuts. They apply an number of torque to a lubricated fastener beyond just what a human could muster, usually together with an impact socket. They were first introduced in the 1960's, but have evolved considerably ever since then as a result of manufacturers constantly updating and advancing their designs. It's lead to the modern hydraulic torque wrench, one which is light as a result of exotic alloys, having a smaller nose radius to increase how many spaces it'll match, possessing multi-position reaction members, and you may even now run multiple tools off of just one power pack simultaneously. Today's modern torque wrenches are optimized for efficiency and flexibility inside their uses.
What makes a hydraulic torque wrench work is that it generates torque using only hydraulic means, it is self ratcheting, and it should have a precise way to measure the amount of torque put on the fastener. A holding pawl design is popular amongst most manufacturers to lock the wrench constantly in place, but each involve some claim that there design is superior. I say whichever one works, works. These wrenches typically have an accuracy rating of +/- 3%, with a high repeatability rate. This makes them suitable for large bolts that want a high amount of accuracy. The biggest advantageous asset of a hydraulic wrench doesn't have anything related to performance, but with those that use them - these torque wrenches are significantly quieter than similar output pneumatic impact wrenches. That is an advantage that you can't measure in strength, repeatability, or work output increases - it is about the fitness of those that use it.
An electrical torque wrench is just a gearbox that is linked to a power motor. This gearbox is made in this way that it absorbs the torque, allowing the consumer to work the wrench with minimal effort. They're typically used if you find no need for torque strength accuracy being used on the nut or bolt, or each time a very stubborn nut must be removed hydraulic torque/tensioner pump. The gearboxes may be of ratios all the way to 4000:1. and this really is adjusted by controlling the voltage. As a result of fact it is powered by electricity, you will find waterproof models for when water is just a concern on the jobsite. It is often confused by having an impact wrench due to its similar design, however it is certainly a completely different tool, and is even more distinctive from a hydraulic torque wrench. Everything comes right down to the job and getting the best tool for it.
