It would originally have been Whitworth. I don't know the size.

    Indeed it is!

    1/4"" Whit  20TPI  into the alloy, BSCy  26TPI  at the nut end.

     In the literature section of this forum you will find a nut and bolt chart, search for the part number of the stud, bolt or nut and there is a good chance that most common fastening thread specs are listed.

 Thanks to Musky for posting the link.

 Cheers.

 Swarfy.
