Goes round when using the right nuts (5)
I believe the answer is:
turns
'goes round' is the definition.
'using the right nuts' is the wordplay.
'using' indicates anagramming the letters (the letters used in a different way).
'the right' becomes 'r' (common abbreviation).
'r'+'nuts'='rnuts'
'rnuts' is an anagram of 'TURNS'.
'when' acts as a link.
(Other definitions for turns that I've seen before include "Changes direction" , "Bends" , "Revolves" , "Starts" , "Rotates" .)
