is it 10mm x 1.0 or 10mm x 1.25 ? I have an 82 with drums all the way around. Have looked and cannot find the answer. Anyone know? Thanks.

T....I believe they are 10mm x 1.0 pitch. ...
...Looks like we need part # SB10125 for drums.
Hmmm, I wonder why the sites that sell these things list it as a 10mm for all LCs, whether new/old/disc/drum.
These ones by Russell are $10 for 2 (I think they ar ethe same thing). Interestingly, even though they are marketed for "Disc Front, Drum Rear" - they are the same damn size for both front and rear - 10mm x 1.0

Thanks Tom. I'll let you know if indeed the 10mm x 1.0 is the correct thread.
And let us know what you think of those bleeders at the same time
10mm x 1.0 is indeed the correct size. As for the product itself, they are awesome (well, as awesome as anything related to bleeding brakes can be). Very easy to use and they work well, one-way valve gets air out without letting any in.
Use 3/8 OD 1/4 ID clear tubing from hardware store to catch fluid in a can/jar/cup, fits on the nipple perfectly and prevents making a mess. Brakes are nice and tight.
Highly recommended. I got mine at Summit Racing.
I'm not so sure.
I think you're both right on the thread pitch (1.0mm) because Chris says so here (and he is seldom wrong):

Correction - Chris (Henry James the 47th) said "probably" so obviously he is NOT certain himself.
But I think they could be M7 x 1.0 (not M10)
I don't want to remove one off my vehicle for obvious reasons but holding my vernier callipers against the little bit I see ....... it looks a smaller diameter than 10mm.
And searching the Internet shows that M7x1.0 is used on some Toyota 4x4s (but I see M10 x 1.0 also represented - and possibly even more common!)
But my 10c bet is on #SB7100 if I was to choose one from that supplier BeastII.
Amaurer has a 1982 NZ BJ42 (big drums on front) and I seem to remember that he renewed his wheel cylinders recently. So you could ask him to measure the nipple thread (if he still has an old one lying around) to determine whether it is 7mm or 10mm.
