It would seem that you do need the 12x1.25 lock nuts .

LOCKNUTFLGDM12X125
T3350234
Replaces T3350115

I put a new chain and sprockets on my 2008 Standard Bonneville 865 EFI a couple of months ago and those nuts are M10x1.25 , and the same part number is listed on the schematics for carbed and EFI T100's , so be aware that the supplier you mentioned states T100 as 12x1.25 . You'll need to verify what they're actually sending you . If you can , measure your sprocket carrier stud to make sure .

if you need new M10 x 1.25p nuts use nyloc nuts as they self lock on the thread. besides obtaining from industrial bolt suppliers like Blackwoods that are in most Australian cities, or get them online from this Aussie supplier Stainless Steel A4 Nylock Nut M10 (1.25)
about a $1.50 each

if you want the black finish just color them in when fastened with a Texta or black Sharpie pen

having said that, I've re-used mine several times with no problems. I make sure they are tightened to the Triumph specified 55 Nm torque

Use any style nuts you like with washers. Don't feel you need to limit yourself to self locking. Just use safety wire and loctite with any "standard" nut.
