A 1/2" drive pistol-grip air impact wrench. An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft ...
A hydraulic torque wrench is significantly quieter, lighter weight and more accurate than pneumatic impact wrenches capable of similar torque output, making it an appealing alternative for many users to the very loud and cumbersome impact wrenches or torque multipliers which were formerly the only viable option for working with very large nuts ...
Torque (system unit unit-code symbol or abbrev. notes sample default conversion combination output units Industrial: SI: newton-metre: Nm N⋅m Triple combinations are also possible.
An electric impact driver typically delivers less torque and accepts smaller tool bits than an impact wrench. This makes the impact driver more suitable for driving smaller screws in (for example) construction work, while an impact wrench is preferred in situations requiring more torque to drive larger bolts and nuts (such as lug nuts).
The design allows for higher torque application with reduced camming, slipping out and damaging the fastener. [65] The ECX drive is not compatible with older combination Phillips and slotted head screws. [66] Although Milwaukee Electric Tool holds the trade name ECX, their marketing materials do not tell what type of screw head ECX is designed ...

An impact wrench is a device designed to impart torque impacts to bolts to tighten or loosen them. At normal speeds, the forces applied to the bolt would be dispersed, via friction, to the mating threads. However, at impact speeds, the forces act on the bolt to move it before they can be dispersed.
The B-form shank is a variant for high-torque applications, and has a flange one size larger relative to its shaft diameter. (Thus, an A-40 shank will fit into a B-50 socket.) Forms C and D are simplified variants of A and B for manual use, eliminating features to accommodate automatic tool changers like a V-groove and associated orientation ...
