Projecting metal collar to which other members are fixed (6)

I believe the answer is:

flange

(Other definitions for flange that I've seen before include "Projecting (steel) collar" , "A projecting rim or edge" , "Projection used for attaching another object" , "Rim (on wheel)" , "Raised edge of a wheel" .)

I've seen this clue in the Sydney Morning Herald.
