Impact Wrenches In All Industries - ToolsRUs
Nuts and bolts are loosened or tightened by the use of the rotating forces of an impact wrench. The hammering function also allows for additional torque to build. Impact wrenches are available with two main sources of power, air and electrical. Corded and cordless models are both available with electric power.

One use for impact wrenches is when structural steel is put into place. Plumbers, electricians, and heating/cooling specialists all use impact wrenches to bolt their equipment into place. Automotive technicians also utilize impact wrenches to repair automobiles. The vibrations generated by an impact driver, coupled with the high torque of the motor help break accumulated rust and grime loose on nuts and bolts. The anvil speed within an impact wrench can run between 300 and 5,000 RPM's. The user is able to tighten a large number of nuts and bolts to relatively high levels of torque quickly.
Power Sources
The air version of impact wrenches tend to be more popular because they provide a more consistent and higher torque and speed. Electric models have a reputation for not delivering as well in these areas. Now, electric impact wrenches, even cordless ones, can deliver very respectable torque and rotational speeds, in much more portable packages.
Impact Wrenches Can be Used for
Impact wrenches can be used for a variety of things. An impact wrench can handle the job of securing anything with nuts or bolts. Metal frame pieces can be secured when a builder is assembling. Auto techs use them to secure nuts and bolts to automotive frames and suspension pieces. Impact wrenches can be used around the house to secure electrical panels to studs, balcony railings to joists and other similar projects.
Always Use Safety When Using Impact Wrenches
Extensions, sockets, and bits not specifically designed for use with impact wrenches should never be used with them, not even “just this once.” Tools that aren’t designed to withstand the hammering impacts can shatter. Wash or glove hands with chemicals on them to ensure you have a tight grip before using an impact wrench.
