Which locking nuts fit behind OZ centre caps

[McTavish]

I was considering purchasing some McGard locking wheel nuts from Halfords, they appear to be of good quality and have good reviews on various websites.

However, they appear quite deep and given the confines behind the centre caps of my OZ split rims; would they fit?

Anyone fitted locking nuts and can recommend these or other makes?

I had the same problem when I swapped the Estorils on my 500 for some Oz pre cat cross spokes. The wheel nuts and locking nuts I had fitted fine on the front but did not fit under the cover on the rears - I got some shorter nuts from TVR dealer but could not find locking nuts anywhere. So I got my hacksaw out and performed some shortening surgery. That was 18 month ago and no problems since.
