Hex keys are used to fasten internal hex drive screws.
Besides metric hex drives in (half) millimeter steps, non-metric screws are relatively common so make sure the key you are using actually fits! Round keys don't work too well anymore...
There is a large set of metric and inch keys in the metal workshop and some common metric sizes in the grey screwdriver bit set.
