Zenith Adjustment Needle Housing

I used to know this but it has slipped away. It's not the age, it's mileage.
The Adjustment needle housing has an odd sized hex wrench surface for install and removal. Can someone with a memory better than mind let me know what sized wrench to go in search of? My tools have been jumbled by a move and I need to rebuild some Zeniths this spring.

Thanks to all
 
You can also take a Craftsman 10 mm box wrench and a triangular file and file to fit. It doesn't take too much work. Ed
 
Actually, an 11mm 3/8 drive deep socket fits without modification or filing anywhere. (There have also been some reproduction brass housings over the year that just used a 7/16 socket or wrench)
 
i use a metric size wrench, 10mm (i think? i have to check every time i do one. why cant i remember it???..)
