The function of a wrench depends on what type of wrench it is. In general, small flat wrenches have two 'flats' that are sized to particular bolt or nut sizes.These wrenches are used to loosen or tighten nuts onto bolts. The crescent wrench is able to be adjusted to many sizes of nuts and are handy to have in a tight corner when you don't know the size. Ratchet wrenches are used to do up or loosen nuts quickly where movement may be restricted and you have to re-seat an ordinary wrench after each partial turn. Box wrenches have round heads, able to completely encompass the nut and are very useful where nuts are rusted or otherwise extremely tight. Pipe wrenches are usually larger jawed wrenches used to grip large pipe nuts and pipes themselves in Plumbing work.
