I have my new alloys but the holes are smaller so I can't put the standard nuts on as I can't get the wrench round them, but I dunno what i'm looking for as an alternative, re thred pattern and bolt size?

can anyone advise?

EDIT: GOT SOME

Altho I can't find any locking nuts now so if anyone can advise on that one...?

Cheers

EDIT AGAIN: never mind, I got some now
