FK-052 fork 15m nut

[MTB2223]

I started a new project with a new frame (CS-136) and fork (FK-052)from Peter. I'll start a new topic later.
I didn't want a Chinese axles, but a DT Swiss axles, front and rear.
Now I've got the parts I didn't realize the fork is without a integrated nut.
So, who knows which nut I can use in combination with the DT Swiss 15mm axle and the FK-052?

According to extralite (http://www.extralite.com/Products/Black%20Lock.htm) you need M15x1.5 nut. Problem is that , since almost always nut is integrated in the fork, nobody uses separate nuts. Only thing I found on R2 was https://r2-bike.com/SHIFT-UP-Thru-Axle-QR15-for-Carbon-Rigid-Forks.
