It is a M8 nut I believe, I made mine but I forget the pitch, just the regular pitch I guess.
I installed the new Alarm Siren which also chirps with the remote door Lock and Unlock
I needed a gear puller tool to remove the wiper arm from the posts
I also needed a nut to secure this new alarm siren as it has a threaded stud to attach to the existing bracket
The nut that hold the wiper arm is the same one you will need for the siren to attach it to the bracket
I didn't have a Torx bit to remove the Torx security screw that held the OEM siren so I simply turned the siren itself to loosen it from the bracket.
A photo below shows the "Torx Security Screw" in the old siren
