Description Here’s a rare one! This is the nut that was found on early 1 3/8″ diameter clawfoot tub waste and overflows. Supplied with a rubber square cut washer, four finishes available. Note, BE SURE to check thread pitch. These nuts are 11 1/2 TPI. Before WW1, there were multiple thread pitches, and we ONLY have the 11 1/2″ version
