Thanks - will use EN16.

Silver steel is a definite NO for wheel spindles - it's much too brittle. Something like an EN16 is much more appropriate. I'm sure your machinist can advise.

Thanks Paul,
I had more or less come to that conclusion. I just wanted a bit of reassurance on the thread form before committing to getting some made.
I have a drawing which has been compiled from the damaged parts which came with the project bike (I also have an identical bike which has good axles) and I intend to have the end caps made in stainless steel, using a silver steel axle and stainless fixings.

7/16" CEI and above can be obtained in 20tpi as well as 26tpi. See B.S.811:1951. Your 9/16 X 20 axles are almost certainly   CEI.  There are several suppliers of both SS and zinc plated fasteners to the 20tpi standard.

Hi All, and Happy New Year!
My 1932 Lion project needs new axles, and I need to confirm that the thread form is CEI.
The axles are 9/16 diameter and 20tpi.
I'm sure someone here will know for sure.
Thanks
