You can have a look at ?gpar (after loading package 'grid').
For example, your original request could be handled with
setting lex=2, but that would thicken all lines including the
axes and tick marks.

I'm not sure that my advice was the best; it's just what
occured to me at the moment. Perhaps Deepayan will weigh in
with the definitive solution.
