Marina van front hub

[Pauliil1948]

Hi guys ,
Trying to find the thread size on the marina van hub , I have got 2 sets of nuts but don’t fit
Set 1 is 3/8UNF and are to small
Set 2 is 1/2” UNF IS TO BIG
Need to find correct ones any help / advice would be great

7/16 UNF more than likely if a 10cwt could be a old BSF thread due to age of rear axle my best bet would be 7/16 though

It is 7/16” UNF. The 10cwt/575 nuts are Triumph part number 109586 - same as the steel wheels on Triumph 2000/2500 & Stag.
