Tank screws A65

[jgfabs]

Hi, im new, i have an A65 tank without badges which are coming.Does anyone know the size of screw to attach them to the tank please?

You will need to say which year your A65 tank is - the fixing screws varied over the years.

Ah,...ok.
That im not sure of as its a replacment mild steel tank for my 66 Hornet,as i wanted a slightly different look.
I assume there something imperial equivelent to an m5 or similar?

For a 1966 tank with pear shaped tank badges, the 4 x screws were: 11/16" Long, 1/8" Diameter with a Thread Pitch of 40 TPI (6BA)

I believe that the tank badge screws were 1/8" Whitworth which is 40TPI.  BSA part number was 82-8250.

The part numbers were:

65: 68-8090
66/67: 40-8125
68/69: 82-8250

Need to look them up to see what the differences were.

Yes, the earlier part numbers (68-8090 and 40-8125) were for the plastic badges and I should have qualified my response that 82-8250 is for the metal tank badges.  I have noticed that a retailer has advertised 40-8016, 40-8125 and 68-8090 as 3BA.
