Definition:
A "wing nut" is a type of nut (a small piece of metal) that has two flat parts sticking out, like wings. This design makes it easier to turn the nut by hand, using your fingers, without needing any tools.
In more technical contexts, "wing nuts" are often used in construction, woodworking, or any situation where you need to quickly assemble or disassemble equipment without tools.
In a more informal context, "wing nut" can also refer to someone who is considered eccentric or crazy in their ideas or behavior. For example: - "He's a bit of a wing nut when it comes to conspiracy theories."
There are no specific idioms or phrasal verbs that directly relate to "wing nut," but you might hear the term used metaphorically to describe someone who has unconventional ideas.
A "wing nut" is useful for tightening or loosening things without tools, thanks to its wing-like shape.
