Maillard hub - axel thread pitch?

Ready! SHOOT!! ….aim…
I noticed pitting on my front hub cones. So I took some measurements and a few assumptions and ordered replacement cones from ‘no-returns Wheels Mfg.’ with confidence only a masters in mechanical engineering can provide.

The new cone pitch does not match the old axle.
The new cone is listed as 9mm diameter by 1mm thread pitch.
I think the axel is about a 0.9mm pitch. (Measures about 11threads over 10mm…)

Anyone know this minutiae for sure?
Anyone want to buy a new set of cones? See pic. Free shipping!….no returns….
Any suggestions at this point?

I couldn’t find an answer scratching around the internet. A new axle is $40. Heck, I can buy a set of Shimano hub for $55- and no more French stuff to torture me!

I suspect the Maillard axle is a 26TPI pitch. A replacement axle, that matches the cones, might be the easiest way to go forward.

I will say that better service focused shops often save old parts that are otherwise still functional. A 9x26 axle might be in an old parts bin locally. At one time this ft axle spec was about the most common in use. Andy

I just checked if QBP had a 9x1x110 QR axle in stock and they do. But I was not expecting such a high cost. I guess I've been away from the supplier chain for too long. Last time I had to order one for a shop the whole sale cost was about 1/4 what it is now...

AS said it might be a 3/8 axle. https://www.greenwich-market-trader....m.php?ITM=3376

thanks for the link, dedhed - my calipers are measuring the OD of the axle at 9mm even steven. 3/8in would be 9.5mm (and a little change). Wheels Mfg. sell 9.5mm.

Andrew R Stewart - I believe you are correct on the 9mm x 26tpi. I can start (by hand) to put the new cone on the old axle, but after a few rotations, it starts to bind. The old cone goes pretty freely.

Wheels does sell these: https://wheelsmfg.com/products/hub-p...read_size=6224 (so another $25 into this....)
OR, I rebuild the wheels with these when the hubs are completely blown:
FS: Shimano 105 Hub Set, Dark Finish

thanks, y'all!

Sutherland notes that Maillard 700 rear axles are a unique 10mm x 0.75mm (I have a rear with a broken axle and good cones )

Sutherland does not say anything about the front, and I would not be surprised if it is something equally oddball. But 9 x 26 is more likely. (Why did anyone ever do metric diameter with imperial thread pitch?)
