🦋 Overview of Butterfly Screws
Butterfly Screws, also known as Wing Screws, are specialized fasteners designed for effortless hand-operation. Featuring a larger lateral force surface, they allow for high-efficiency tightening without the need for additional tools.
🛠️ Key Applications
✔Display Industry: Used for securing various display components.
✔Automobile Industry: Ideal for components requiring frequent dismantling and insulation.
✔Aerospace Industry: Applied in electronic equipment for insulation and anti-interference.
✔Office Equipment: Used in the production of rust-proof and aesthetic office hardware.
✔Furniture Assembly: Secures sofas, beds, and wardrobes while remaining easy to adjust.
✔Lamp Installation: Provides fast and convenient fixing for lighting fixtures.
✔Home Decoration: Perfect for wall ornaments, murals, and clock installations.
✔Construction: Suitable for architectural decorations and fixed furniture.
🔬 Material Performance
These screws exhibit excellent oil and chemical resistance. When used as mechanical materials, attention should be paid to their hygroscopicity, as moisture may affect tensile strength, permeability, and ductility. For enhanced outdoor performance, carbon black can be added during injection molding to improve weather resistance and high-temperature stability.
✨ Product Advantages
01
Deep threads and even tooth pitch ensure uniform force and superior fastening strength.
02
Smooth surface finish with no burrs, showcasing delicate craftsmanship.
03
Strictly controlled raw materials with exquisite grinding for high hardness and durability.
❓ Frequently Asked Questions
What makes Butterfly Screws different from standard screws?
Butterfly Screws feature a unique wing-like head that provides a larger lateral surface area, allowing users to tighten or loosen them by hand without tools.
Can these screws be used in outdoor environments?
Yes, especially when treated with carbon black during molding to enhance weather resistance and high-temperature tolerance.
Are Butterfly Screws resistant to chemicals?
Yes, they are designed with materials that offer significant resistance to oils and various chemicals, making them suitable for industrial use.
In which industries are these fasteners most common?
They are widely used in the display, automobile, aerospace, furniture, and office equipment industries due to their ease of removal.
How does moisture affect nylon-based butterfly screws?
Moisture can increase ductility and impact strength but may reduce the overall tensile strength and permeability of the material.
Do these screws provide a secure hold?
Absolutely. The deep threads and even pitch ensure that the fastening force is distributed uniformly for a secure grip.
