Daryl~ Take a look at the EJOT line of fasteners: http://www.ejot.com/ejot.de/EJOT_Solarbefestiger_Bau_2009--2749,websiteLang__en.htm
These sort of look like a "hanger bolt" but they are machined to cram down on a fat rubbery washer as they are tightened. EJOT is showing up in some of the PV wholesaler inventories, and there are fastener companies with inventory in the US. Contact me off list if you have trouble finding a supplier via normal channels, and I'll think of a source or two to which I can point you.
