Hi I need to remove a rad tail to change the valve, what size allen key do I need? I've narrowed it down to these:
http://www.toolstation.com/shop/Han.../Rad+Valve+Spanner+127mm+hex/d10/sd210/p90498
http://www.toolstation.com/shop/Han...ner+Air+Release+Key+12mm+Hex/d10/sd210/p63865
http://www.toolstation.com/shop/Hand+Tools/Plumbers+Tools/Radiator+Hex+Key/d10/sd210/p26053
Will they all fit, I notice there's a 0.7mm difference in size between two of them. The rad is over 10 years old if that makes a difference!
Thanks
