A second major variety of compressed air powered tools are impact wrenches which are used for common tasks such as lug nuts on wheels. Electric powered impact wrenches for the same tasks are not uncommon. Small cordless 12 volt and 18 volt impact drivers are often used today as powered ratchets to remove and install nuts and bolts.

some flexibility in tolerances, it is common to see two manufacturers make deep sockets of the same size but with slightly different depths even though both meet the same specification. Standard length, otherwise known as "shallow" sockets, have a lower profile and allow a user to access nuts in narrow spaces.

By attaching to the outside of the socket they also allow the socket to be built up to 50% shorter and with 20% less width which is an advantage in some situations. Pass-through sockets and ratchets are built for

Some sockets are designed to have the same outside diameter and shape within a given set size.
