A bit off topic but I'm building a 50A 12V DC power supply. Purchased 50A thermal overload breaker panel mounted push button reset on ebay. Though in the photo the knurled nut was on the breaker it was not included. I contacted the seller and was told not included, I mentioned the photo included the nut. My option was to return it for full credit or $3 credit. I took the $3 so as not have to bother returning it.
However in checking thread size I'm coming up with 11mm or 7/16" But thread pitch is either 1mm or 25tpi. My thread gauges don't seem to fit quite right, threads are not the cleanest. I put it on optical comparator and 1mm seem to be the best guess. Does anyone know what size knurled nuts are available? Ebay as a few, those with size and pitch and not near what I need though 7/16" is available but thread pitch not listed. Others are listed but rather than size application is listed. 11mm X 1mm Tap is available probably from China.
