wing screw
Học thuậtThân thiện
Definition
Noun: A type of fastener, specifically a nut, that has two flat, wing-like projections. These projections allow the nut to be tightened or loosened by hand using the thumb and forefinger for leverage, without the need for a tool like a wrench.
Usage
This term refers specifically to the fastener itself. It is a compound noun where "wing" describes the shape of the projections and "screw" is used here in the sense of a threaded fastener (though technically it is a nut, not a screw). * You secure the panel with a wing screw. * The wing screw was loose, so I tightened it by hand. * The design uses wing screws for tool-free assembly.
Advanced Usage
- Technical Context: In mechanical and assembly contexts, a wing screw is chosen for applications requiring frequent adjustment or disassembly where tools are inconvenient. It is a type of "thumb screw."
- Specification: When ordering parts, one might specify the thread size, material, and finish of the wing screw (e.g., "a stainless steel M6 wing screw").
Variants and Related Words
- Thumb Screw (Noun): A very close synonym. While all wing screws are thumb screws, some thumb screws may have a different head design (like a knurled head) instead of wings. The terms are often used interchangeably.
- Wing Nut (Noun): A related but distinct fastener. A wing nut is also hand-tightened but is designed to mate with a bolt or threaded rod. A wing screw typically has its own integrated male or female threads and is often used as a standalone fastener or clamp.
- Butterfly Nut (Noun): Another synonym for wing nut, emphasizing the wing-like shape.
Synonyms
- Thumb screw
- Hand screw
- Winged nut (less common)
