I have a mast gate held in position on the mast by a screw with a knurled head. The thread has stripped in the mast so I want to either get a rivnut to insert or drill a new hole and tap it. Problem is I can't identify the thread. The diameter of the thread is near as dammit 6mm (measured with a 6mm spanner which just fits over the threads). The pitch appears to be 1.25mm measured by taking a photo and exploding it to calculate the pitch from the diameter.
The boat is 1978 vintage. Anybody got any ideas please.
