Socket wrenches are good for working on automobiles and other machinery.
Although standard-size sockets are fine for most applications, deep sockets are available for situations where the bolt is recessed. Both can turn nuts in tight spaces. Self-adjusting wrenches automatically adjust to fit the size bolt you're working on. These wrenches are self-ratcheting, meaning you don't have to remove them from the bolts as you're tightening. Adjustable wrenches accommodate nuts and bolts of various sizes.
