Fan set out for tie (6)
I believe the answer is:
'for tie' is the definition.
(I've seen this before)
'fan set out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'fanset' with letters rearranged gives 'FASTEN'.
(Other definitions for fasten that I've seen before include "Fix securely" , "Nail" , "Bolt" , "Attach" , "Close, make secure" .)
