Impact wrenches are widely used in many industries, such as automotive repair, heavy equipment maintenance, product assembly, major construction projects, and any other instance where a high torque output is needed. For product assembly, a pulse tool is commonly used, as it features a reactionless tightening while reducing the noise levels the regular impacts suffer from. Pulse tools use oil as a medium to transfer the kinetic energy from the hammer into the anvil. This gives a smoother impulse, a slightly lower torque to weight ratio and a possibility to design a shut off mechanism that shuts the tool down when achieving the correct torque. Pulse tools are not referred to as "impact wrenches" as the performance and technology are not the same.[according to whom?]

The heaviest tool in the batch is the Matco Tools at 8.02 pounds, with the 4.0 Ah battery.
crow's-foot wrench crow's foot A type of wrench designed to use the same drive sizes as socket wrenches, but non-cylindrical in shape. The ends are the same as those found on the open-end, box-end, or the flare-nut wrenches. These wrenches are used when torque must be measured, or when the application precludes the use of a regular socket or wrench. Also used in place of conventional open/box wrenches where the wrenches are large, usually at a lower cost, or for when space and weight restrictions are critical. socket
