Front axle inside hex size

I'm doing the 1k service on the wife's 2022 FXBBS and the front axle appears to be an inside hex, can someone tell me what size it is?

3/4" if its the same as a 20+ low rider S if you have a 5/8" spark plug socket the wrench side should work.

Do not know the size of your hex; however, I have one of these and it has worked well on the inside hex of my metric bikes

Thanks guys. It works out since 3/4 is nearly 19mm on the nuts.

Just measured my '21 FXBBS. 19.25mm or .7580". There are some variances in tool size. I have both a 19mm and a 3/4" for the job. The 19mm fits tighter, so that's what I use.

Nice. It is a handy addition to any toolbox that deals with larger size hex. I have used mine on my metric bikes axles & some fork tube inserts using a long extension to hold the inner tube in place while tightening the bottom hex screw.
