No comment about the finish, but you might recommend he use Bellville washers on the bolt asseblies.

Happy Monday! I have a customer (we are a fabricator) asking the following question; "..we are looking at making a board that is intended to be bolted to some batteries through 6mm and 8mm nuts and bolts. I was wondering if you have any recommendations on what sort of plating should be on the pads these nuts are going to screw down onto? The batteries are fairly heavy and the apparatus may be subject to some vibration and shock. Thanks for your insight." I am thinking HASL has been used for years in similar applications but does anyone have any experience or are there any studies on the matter?
