What is a rawlplug?
Originally a fibre plug, inserted into a drilled hole in brickwork to allow
a screw to be screwed in. Rawlplug is/was a trade name
- but is now used generically for any such plug. Modern plugs are made of
plastic.

Gotcha. We use the same things here, but I have no idea what they're called.
