Newb question, hub castle nuts 32mm?

Sounds like a strange question but what size are the front hub castle nuts? I only have upto 19mm and will have to go out and buy a special sochet for this so don't want to buy the wrong size. It looks to be about 32mm but I have no way of knowing.

Thanks in advance

Fairly sure it's ~32mm but I will confirm later.

Yes, 32mm. Get a 6 point instead of a 12 point if you have a choice.

 

Thanks to you both! That's all I needed to know. The local store is well stocked so I should be able to get a 6 point no probs, Thanks for the tip!
