Removing and installing bolts for industrial use is pretty tough even for those who know the task well. These bolts and nuts generally are situated in tight and small spaces, where they are hard to reach or where danger lurks. Luckily, an electric torque wrench usually can get the job done. An electric torque wrench is a bolt tensioner of sorts that will loosen up any tightly wound nut or bolt with very little effort on a user’s part. This wrench is gaining a considerable following for a range of other reasons too, including cost, ease of use and quietness.

One nice benefit of an electric torque wrench is that it can easily be plugged into the outlet of any wall socket anywhere. A torque wrench requiring batteries would also require near constant charging, particularly for larger projects or ones requiring a significant chunk of time. Luckily enough, these wrenches come with waterproof versions too, since they are plugged into a wall and therefore output some electricity as they work their magic.

Another unique benefit is the ability of an electric torque wrench to require very little effort on the part of the user. A user just needs to plug in the equipment and turn it on, and then use a tiny bit of effort to get the wrench into motion. Of course, some calibration may be required as well. This cuts down on time and increases the effectiveness of both the tool and the user, since more manpower can be used on other tasks requiring more strength.

Similarly, an electric torque wrench is very silent, compared with other similar tools like a hydraulic torque wrench or a hydraulic splitter. Hydraulic pumps are both hydrostatic and hydrodynamic in their functions, but they can be louder than an electric torque wrench in some cases. While this feature is not normally something that would make or break a purchase, it certainly is worth mentioning. And hydraulic torque wrenches have to be broken in before they are calibrated because they work with both hydraulic and mechanical systems.

An electric torque wrench works similar to a hydraulic flange spreader, which is used most often for medium pressure and high pressure flanges. It also functions like a hydraulic bolt tensioner, which is used for all sorts of stud and bolt tightening purposes. These applications include wind and steam turbines, pipeline flanges, heat exchangers, valve pumps, and reactor and pressure vessels.
