Currently it's hardcoded. You can see it in this line in backend_pdf.py:
https://github.com/matplotlib/matplotlib/blob/9ca2c4118f684b4e145bd109008f77731d2d7cd4/lib/matplotlib/backends/backend_pdf.py#L1061
You could change that line.
However, long term, I think we need to add a hatch_line_width kwarg to
artists -- and perhaps further (though this would break backward
compatibility) separate out the edge color from the hatch line color, so
one could have (for example) a black rectangle filled with red hatching
(not currently possible without layering objects).
Cheers,
Mike
