I dont understand this thread pitch gauge. It says whitworth 55degrees on one side and metrisch 60degrees on the other but when i flip the leaves out it doesnt say which ones are which. Some have G stamped after the number and the others dont. Both types are stamped on the same side and its the metrisch side so all of them are metrisch if you believe the gauge. I think im gonna sort out which ones are metrisch and which ones are whitworth and then take it apart and make it make fukn sense. Then im gonna buy a UN gauge.
