Rim fitting and wheel nuts specification

I'm trying to figure out what is the exact specification for wheel nuts fitted at XE?
I have searched all around the forum, car's owner manual and some sites, but no luck (at least no with consistent information).

What I have found at wheel-size.com for my Jag MY2016 is:
Center Bore: 63.4 mm
PCD: 5x108
Torque: 125 Nm
Thread Size: M12 x 1.5

However, two things bothers me:
1) At some sources I have found that Thread Size is actually M14 x 1.5?! Who is correct and who is wrong?
2) What is the key size for XE nuts, I assume 19 mm (3/4")...? Or maybe 21 mm (13/16")? Probably I can check this myself, but car is not here besides me, and I want to search for proper locking wheel nuts in advance (because my Jag is not fitted with those by default).

Thanks in advance and sorry if I posted in wrong section... I have found the most of discussions related to wheel (locking) nuts in this section, so following that practice.

Thanks very much, guys.

@Fighterpilot Where did you found that specification? Is it available somewhere online?
I have got my answers now, but may be useful in future for other things...

All good, it's only important that we solved mystery. ;)

Today I finally fitted new tires, I put Michelin PILOT SPORT 4 225/45 R18 95Y XL at 18" MATRIX 7 TWIN SPOKE and now I'm finally ready to go.
The only doubt was should I go with 245/40 tires, as workshop manual for MY2017 saying, but I decided to go with recommendation at www.wheel-size.com for my car for rims that I have (Matrix).

@Fighterpilot Thank you very much for this link to workshop manuals.
