Wrench target (3)
I believe the answer is:
nut
'wrench target' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nut that I've seen before include "something turned when making fast > food" , "Freak" , "Fanatic (slang)" , "Almond, for example" , "Brazil, for instance" .)
