9mm -mutter, grumble....
Or revert to the well tested and tried plan B: Drill the 10mm hole, cut a
square piece of wood slightly bigger than depth and diameter of hole, cut a
small lead-in taper on the end, bang timber plug into wall, cut off to
length with a chisel and then insert screw (pre-drilling hole in plugs as
necessary).
Sounds like a lot of needless ****ing about to me
