Hi all
I have ordered some of these :-


So I am puzzled as to why the mounting hole's are M7 ?

Is that because I am meant to use M6 and it gives me some wiggle room ?
Or
I am meant to buy M7 ?
Or
sod it and carefully file them out to M8 and make the mounting holes in the tubing a little bigger if I need wiggle room ?
answers on a postcard to the usual address .........
