oh yes.......see what you mean.......thats stumped me,any foccers know the answer ?...........6 / 8 mm parhaps,thats a guess ..........if you can get one of the studs out before you go to b & q,you will be sure to get the right one,but thinking about it you would have to make the hole bigger in the header collar :eek ...it would still work thoughÂ

One, is never going to be enough.....
