Terzo/Turbo 2000 Wheel Nuts
 

My recently acquired Terzo did not come with a Wheel Nut wrench.

I want to buy one, but can anyone tell me the correct (hex) size of the nuts please?

I have a number of socket sets but none of the sockets fit because of the dome/rounded ends of the nuts.

I will need to buy a "deep" socket but do not know what size to get.

Thanks in advance for any help.

19mm and approximately 65lbft of torque should do

Thanks for that.
