While pistol impact wrenches are bulkier, their grip style is more ergonomic to prevent strain on your hands, which in turn allows you to work for longer periods without fatigue. Some of these models can equip side handles which let you use your weight for greater leverage and to maintain a proper working angle. If you don’t need the special fit of an inline wrench, a pistol-style impact wrench is usually the ideal choice.
A total length of barely 5 inches and a weight of less than 3 pounds means this tool is one of the few things around that is actually smaller than your Dad’s… ego. Jokes aside, if you need a tool to fit into tight spaces, this could be the one for you. It also boasts a comfortable ergonomic grip, a 3x speed power selector for effective control and the brushless engine we like to see.

The hammer mechanism in an impact wrench needs to allow the hammer to spin freely, impact the anvil, then release and spin freely again. Many designs are used to accomplish this task, all with some drawbacks. Depending on the design, the hammer may drive the anvil either once or twice per revolution (where a revolution is the difference between the hammer and the anvil), with some designs delivering faster, weaker blows twice per revolution, or slower, more powerful ones only once per revolution.


A useful accessory for a socket-wrench set is a handle equipped with a mechanism that measures the amount of torque, or turning effort, exerted by the wrench on the nut or bolt. One type of torque handle has two arms attached to the head, which carries the socket that fits the bolt or nut to be tightened; one arm carries the torque-indicating scale and remains fixed relative to the head, while the other arm carries the handgrip and is bent, relative to the head and the scale, when a bolt is tightened. A pointer on the bent arm indicates the torque on the scale. The purpose of a torque wrench is to make sure that screws and bolts in bolted assemblies are installed with sufficient tightness to prevent loosening during use, without being overtightened.
