What size allen wrench for Rega headshell?

I'd like to remove the 3rd bolt and try a different alignment. Anyone know what size allen wrench to use? I also may want to replace my Exact 2 at some point. What do I need to do this?

Thanks

 

hi Jon

the standard size for the headshell bolts are 2mm allan key

you sometimes get them free with your cartridge...so check your old cartridge boxes 1st

hope that helps
