My staking set (a clockmaker's tool) made by Favorite of Switzerland has a damaged thread on the stud that locks the turntable and I want to replace it. The thread is 6.97 mm diameter x 1.0 mm pitch but I can't find it listed in Tubal Cain's book or the Zeus tables. Can anybody tell me if this is a standard thread that I might be able to buy a die for? Would one in fact refer to this thread as 7 mm?
Cliff Coggin.
Yes.
The standard pitch for M7 is 1mm. But M7 is no (longer) standard. :-)

On or around Mon, 26 Jan 2009 18:33:21 -0000, "Cliff Coggin" enlightened us thusly:
as they've said, M7x1, which is in fact metric coarse, I believe. The only others 7mm in my list are Loewenhertz which is 1.1mm pitch, and M7 fine which is 0.75mm.
nothing else is near that diameter.
Also many bicycle bits use M7 (brakes iirc, mainly French and Italian but maybe also the Japanese)
The 5.5mm hex key needed to remove them that nobody usually has is the clue :)
The rest of the usual sequence being
hex Thread
4mm = M5 5mm = M6 6mm = M8
Wait a moment while I check what cars are on the driveway. A couple of Rollers, several Mercs, the odd Lambo, a brace of Fords, but damn me, no Peugeots. Suppose I'll have to buy a 7 mm die instead :)
Cliff.
And one (ONE only) of the timing belt cover screws - the other four are M6 - yeah! Bloody French! DAHIKT

Yes it was also a standard thread on Renault in the 70s I bought one to tap out a broken bleed nipple. Cheers Colin

----------------------------------------------------------------------- Thanks to all who replied. I found this size for sale at Tap & Die Co. The price was a reasonable £7.50, though tax and postage added a whopping £11.
