They are perfect for electrical and mechanical contractors, general contractors, cabinetmakers, automotive shops, steel workers, construction companies, aircraft and ship building companies and HVAC professionals.  They are used whenever a super strong connection is needed such as putting an aircraft together. That is not the time you want a less than superior connection.  Power wrenches make sure those connections are as they should be.

What Makes a Good Power Wrench?

The basic mechanization principles are the same from one impact wrench to another but there will be differences in the features.  The main features that you want to look for when shopping for an impact wrench or power wrench are listed below.  These are the features that will make one power wrench stand out from the others.

Power Wrench kitA power wrench has three main types of power sources that a power wrench will have: compressed air, electricity and hydraulics.  If the power wrench is being used in construction and automotive work, you will find that the compressed air and electronics is most often used.  The hydraulics power wrench is most often used in heavier industrial applications.

A lot of automotive shops use compressed air power wrenches.  The air tank is connected to the wrench and provides a power source that helps the wrench generate a huge amount of torque for the heavier jobs that the automotive industry involves.  Because of the lack of electrical power source, the power wrenches that are air compressed are more lightweight. You will need a tank of compressed air on hand to use them though.

The power wrenches that use electricity also have plenty of torque but they are not as strong as air compressed power wrenches.  The electrical power wrenches are perfect for home workshops where having compressed air tanks around may not be possible.  Being able to plug the power wrench into an outlet is much more practical for smaller jobs and home garages and workshops.

For the power wrenches that use hydraulics, they provide a huge amount of torque which is why they are used for the heavy duty jobs like big construction sites and industrial manufacturing centers.
