I'm hoping with this disclaimer from the sticky "This board is for wick materials and techniques; wire materials and sizes; O-rings; or any other widgets or doofers* that go in an rba" that I am posting in the right place. I would like to have a selection of different screws that go in RBAs in my building kit, o rings too really. Where can I find them? I have the original backups that came with each atty but I know I'll need more eventually, I'd rather have them before I need them. I briefly looked on FT but maybe I wasn't using the correct search term to pull up the correct items.
