Bottom Plate Screws
These work just great for Boss pedals. They are quite a bit darker (or 'blacker') than what vintage Boss pedals used. However, they work great, and are so 'inexpensive' that it's silly not to have a small amount of these on hand. You know you WILL lose a few, especially if you are like me, and either buy a lot of used pedals, and/or like to take 'em apart more than once.
