9.5mm AXLE THREAD PITCH

[john]

Hi all

I have a 9.5mm axle that I need nuts for. It's for a Taiwanese "TOV"
costar brake hub. I cannot determine if it's 9.5mm X 24tpi or 9.5mm X
26tpi. I've checked Sheldon's site & an old Sutherlands. I have a
metric thread gage w/ templates at 0.90 mm pitch; 1.0mm; 1.25mm; but no
SAE gage. 26tpi calcs out to 0.98mm & 24 to 1.06mm. The 1.0mm pitch
gage seems close, but not perfect. From Sutherlands I suspect its 9.5mm
X 24tpi. I doubt they are interchangeable?

Any thoughts? John

almost all CB are 3/8 x 24

Thanks, Andy
9.5mm & 3/8" are interchangable so long as the pitch is right. Correct?

9.5mm is .374" Vs. .375" for 3/8".

9.5mm is not a metric standard thread size so the axle is probably inch
size to begin with.

Most Asian countries used to follow British "Imperial" thread standards
for bicycles perhaps because Raleigh exported so many bikes to those parts
of the world.
