Well, just to confusticate some more, in the UK they're called 'core plugs'.
A welch plug is an altogether different animal, it's a domed steel disc
which is fitted into a counter-bored hole and tapped on the dome with a
hammer to increase its diameter to seal into the hole. Available in
different sizes, but I can't think just now of where one is fitted on a
Triumph...
