Hey, i think you will find the answer here

First time building thru-axle. Tips and tricks appreciated

[a04c683344e1fca9c2fe23960701c560c22a9f1f] The inside of the disc tab is 4mm from the dropout face. I’ve tried to draw the measurements on the photo. Hope it makes it easier to understand whats going on. If not I can take some better photos tomorrow
