Hugh: I know enough about thread design to think that the .8tpi pitch designation you have indicated might be wrong. The Whitworth set you have I have - The 4.5 mm x .8tpi sounds a bit strange? .8 threads per inch? Can you clarify this for me. I do not think this is possble unless that is .8 thread per mm??? Which inevitably converted would be 20 tpi which I think is correct. Let me know. SAM Buscemi
