I want to remove a bolt which takes a 4mm hex alan key - well it's
not quite that simple. The hex hole has a central pin which prevents
the insertion of a standard alan key. It may be a useful security
feature but nobody knows the wherabouts of a suitable key so it's a
problem.

Ayone know if suitable alan keys can be obtained anywhere? I can't
find such things via screwfix.

Whats "Alan" (Allan) got to do with it? ;-)
What type of central pin? a pic would be nice.
