Screwdriver component (5)
I believe the answer is:
vodka
'screwdriver component' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for vodka that I've seen before include "Russian alcoholic drink" , "Alcoholic spirit of Russian origin" , "Basis of a Bloody Mary" , "Spirit traditionally made from fermented grains or potatoes" , "Spirit made from rye, wheat or potatoes" .)
