Just to let the group know, I too have scoured the Internet unsuccessfully for this type of washer. So I found these guys and thought I'd pop the question. I haven't had a reply yet (only just sent it), but when I do I'll post back here.
Hi,
Ref: http://mrwasherman.com/index.html
Many builders of RV series of aircraft attach the fibreglass wingtips to the wing using #4 countersunk screws rather than the specified pop rivets. However, this causes problems with the paint finish if the tips later have to be removed. Many builders have searched the Internet, unsuccessfully for #4 100 degree countersunk stainless steel tinnerman-type washers for this application.
Do you make such a washer? If so, how much are they and in what quantities.
If not, can you make such a washer? Again, how much would they be and what minimum order would be required?
If you are able to assist I shall post a message in the VansAircraft Forums with your information so that builders know where they can get these washers. As for myself and another local builder here in NZ, we'd need two hundred or so of them (100 each). Let me know.
Thanks,
