Screwdriver need (5)
I believe the answer is:
vodka
'screwdriver need' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for vodka that I've seen before include "Basis of a Bloody Mary" , "Strong drink" , "Russian alcoholic drink" , "Alcoholic spirit of Russian origin" , "Booze" .)
