A Butterfly Nut, also known as a Wing Nut, is a hand-operated fastener designed with wing-like projections on both sides. These wings provide a convenient grip, allowing the nut to be tightened or loosened by hand without requiring a wrench or other tools.
Butterfly nuts are ideal for applications where components need to be assembled and disassembled frequently. They are commonly used where quick access, easy adjustment, and convenient manual fastening are important. Depending on the application, they can be used with or without a washer.
