A propeller fastener (5)

I believe the answer is:

screw

I believe this is a double definition.

'a propeller' is the first definition.
(I know that screw is a type of propeller)

'fastener' is the second definition.
(I know that screw is a type of fastener)

(Other definitions for screw that I've seen before include "Hack" , "Wood fastener" , "shot in pool hall" , "Prison guard, colloquially" , "Propeller; fixing pin" .)

I've seen this clue in The Irish News.
