: Read a novel recently and came across a sentence " He purposely left one screw loose". Is "to leave one screw loose" a phrase? Please help.

If you have a screw loose, then you are a little bit crazy. If you leave a screw loose, then you are not very good at using a screwdriver. In other words, "leave a screw loose" is literal an not an idiom.
