Wing screw stainless Introduction:

The wing head thumb screw is made of stainless steel material, with a wing shaped design for the head. It can be manually tightened and loosened with the thumb and fingers without the need for tools. It is a threaded fastener that combines convenience and weather resistance, and is widely used in various connection scenarios that require frequent adjustment or convenient disassembly.


Wing Head: The core identifier refers to the screw head with two flat, symmetrical "wing shaped" extensions resembling butterfly wings (also known as butterfly heads). 

Thumb Screw: Emphasizing the operation method, this screw is specifically designed for manual tightening, adapting to the force range of the thumb and fingers. It is easy and effortless to operate, even in small spaces where tools cannotbe inserted. Essentially, it is an exclusive classification for manually operated fasteners.

Stainless Steel: The designated core material of the product is different from wing shaped screws made of carbon steel, brass, and other materials. It focuses on the advantages of corrosion resistance, rust prevention, and high strength, and is suitable for wet, outdoor, chemical, and other scenarios that require weather resistance of the material, extending the product's service life.
