A Wing Nut is a type of fastener that features two "wings" or protruding tabs on either side of the nut, allowing it to be tightened or loosened by hand without the need for tools. The wing design provides a comfortable grip, making it easy to install and remove in applications where frequent adjustments are necessary. ... Wing nuts are typically used in situations where a fastener needs to be quickly secured or removed, such as in machinery, automotive, and electrical applications, or in areas like furniture assembly or equipment that requires regular maintenance. They are commonly made from materials like steel, brass, or stainless steel, offering durability and resistance to corrosion.
