May be a bit of a kludge, but you can get a hex to 1/4" square drive adapter
and a set of 1/4" hex socket wrenches, both English and metric, from auto
parts stores like NAPA or probably from Sears. This would give you lots of
size options as well as the capability to use them with your socket set.

Does any one know where I can get a 4mm hex bit for a cordless

Try a good bicycle shop. 4mm and 5mm hex fasteners are THE most
common sizes on modern bicycles.

They may have to order it.

or try Park Tools - www.parktool.com/tool_indexes/catindex.shtml
when my son was a bicycle mechanic most shops used their tools.
