Butterfly bolts are usually a type of bolt with a butterfly-shaped head and are used in applications that require rapid manual entry and removal, such as the installation of electronic devices or other devices that require frequent disassembly. Butterfly bolts are designed to be easily screwed in or out by hand without the need for additional tools. Such designs are useful in situations where frequent maintenance or replacement of parts is required.

Butterfly Screw, also called Butterfly Screw, is a kind of screw designed to facilitate hand-screw operation, with a larger lateral force surface, so that tightening operation more efficient. It has a wide range of applications, including but not limited to:

1. display industry: for fixed display components.

2. automobile industry: for the need for insulation and frequent dismantling and maintenance of automotive components.

3. aerospace industry: Used in electronic equipment on the insulation and anti-interference treatment.

4. Office equipment industry: for the production of never rust and beautiful practical office equipment.

5. furniture assembly: for the fixed sofa, bed, wardrobe and cabinets and other furniture, to ensure stability and firmness, while easy to remove and adjust.

7. home decoration applications: for wall decoration fixed, home ornaments hanging, murals and clock installation.

8. Construction Field: suitable for the fixing and installation of buildings, such as furniture, wall hangings and decorations.

The oil resistance and chemical resistance of butterfly screws make them suitable for use as mechanical materials, but they need to pay attention to their hygroscopicity, because moisture may reduce the tensile strength of nylon, permeability and improve ductility, impact strength and energy absorption properties. In injection molding, carbon black can be added to improve the outdoor weather resistance of nylon, so that it can still work under high temperature environment
