I need a pair of 4inch brass/stainless bolts or set screws. They'll be submerged so the usual BZP or YZP wont do. I can't find any ... at the moment it looks like I'll be using threaded bar - but on the off chance has anyone seen any?

The longest M6 Set Screw they do is 60mm - the coach bolts are square cut and aren't fully threaded. (they were the second place I looked).

I'll have to grab the cheese heads off Ebay, work has got in the way of me finishing the project so theres no hurry at the moment.
