Chris.

My measurement of the terminals on my 19 set switchboard (approximately 1/4-25) suggested BA threads and the 0BA nuts I ordered fit perfectly. Since a 11 set component should be earlier than 19 set, it seems reasonable to me that an 11 set switchboard would also be BA threads. My source for the 0BA nuts was http://www.britishfasteners.com/inde...0ba-steel-3665
