27mm or 21mm nuts
I’ve seen adverts for defender wheel nuts size 27mm and 21mm. Mine are 27mm on steel wheels.

I need a set of nuts for new boost alloys, will both 27 / 21mm fit? Obviously different wrench size to use them!
Thank you

My boosts are on 27mm nuts. My range rover alloys were 27mm too.

I thought that all genuine Defender wheel nuts were 27mm?

Given that the studs are M16 find thread, I don't see how a 21mm AF nut would be possible.

M16, ISO 4032 metric nuts have an minimum across flats dimension of 23.67mm. I wouldn't like to think that my wheels were held on by 21mm AF nuts, a material thickness of only 2.5mm would not give me much confidence. Defender 90XS SW

1 and 7 may look very similar, so could be a typo during data entry.
27mm is the normal size for Defenders up to 2016. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing
