Air Impact Wrench

An Air Impact Wrench uses a high-pressure air motor to drive the impact mechanism, making it suitable for tightening or loosening nuts and bolts. It is widely applicable in various industries, such as automotive repair, heavy vehicles, off-road vehicles, trucks, and buses for tire changes, as well as industrial assembly lines, diesel engines, and agricultural machinery maintenance. It is particularly favored in the petrochemical, cement, and shipbuilding industries.

Frequently asked questions

What drive size air impact wrench do I need?

1/2" drive suits passenger cars and general maintenance, 3/4" drive suits light trucks and larger bolts, and 1" or 1-1/2" drive is used for trucks, heavy equipment and industrial bolting.

What is the difference between twin hammer and pinless hammer mechanisms?

A twin hammer delivers two balanced impacts per revolution for high power with low vibration. A pinless hammer has fewer moving parts and delivers smoother impacts. Learn more in our guide to hammer mechanisms.

What air pressure does an air impact wrench need?

Most industrial air impact wrenches are rated at 90 psi (6.2 bar). Use the minimum hose size listed in each product's specifications to avoid pressure drop.
