China Galvanized butterfly bolts, galvanized union bolts, grade 4.8, grade 8.8 Manufacturers, Factories
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 (Wing Screw): Designed for manual hand-screw operation, these screws feature a large lateral force surface that makes tightening and loosening significantly more efficient without the need for specialized tools.
⚙️ Industrial Applications
Display Industry: Fixed components
Automobile: Insulated & frequent maintenance
Aerospace: Electronic equipment anti-interference
Office Equipment: Aesthetic & rust-free parts
Furniture Assembly: Sofas, beds, and wardrobes
Lamp Installation: Fast and convenient fixing
Home Decoration: Murals and wall ornaments
Construction: Building decorations & hangings
💎 Product Features
Precision Threading: Deep threads and even tooth pitch ensure uniform force distribution and excellent fastening performance.
Smooth Finish: Expert workmanship ensures a smooth surface with no burrs, making them safe and comfortable for hand operation.
Superior Durability: Strict raw material control and exquisite grinding result in high hardness and mechanical reliability.
Technical Note: These screws offer excellent oil and chemical resistance. For nylon variants, care should be taken regarding hygroscopicity, as moisture can affect tensile strength and ductility. Carbon black may be added to injection-molded components to enhance outdoor weather and high-temperature resistance.
Frequently Asked Questions
1. What is the main advantage of using butterfly screws?
The unique wing-like design provides a large lateral force surface, allowing users to tighten or loosen the screw by hand without needing screwdrivers or wrenches.
2. Are these screws suitable for outdoor use?
Yes, especially when treated with carbon black or made from corrosion-resistant materials, they provide excellent weather resistance and can withstand high-temperature environments.
3. In which industries are butterfly bolts most commonly used?
They are widely used in the display, automobile, aerospace, furniture, and construction industries where frequent adjustment or manual assembly is required.
4. How does moisture affect nylon-based butterfly screws?
High hygroscopicity (moisture absorption) may reduce the tensile strength of nylon but can improve its ductility, impact strength, and energy absorption properties.
5. Do these screws provide a secure hold?
Yes, the deep threading and even pitch ensure that the fastening force is distributed uniformly, providing a stable and firm hold for various applications.
6. Are the surfaces of these bolts smooth?
Absolutely. Our products undergo exquisite grinding to ensure a smooth finish without burrs, preventing injury and ensuring ease of use.
