Product Description
Knurled wing screws are typically made of metal materials such as carbon steel, stainless steel, or alloy steel. They are precision-machined with a wing-shaped head and a knurled texture. The knurled pattern provides better grip, allowing users to easily rotate and disassemble them by hand without tools, making them particularly suitable for applications requiring frequent disassembly and assembly. Their wing-shaped design facilitates operation in confined spaces, especially in compact environments, improving assembly and disassembly efficiency.
These screws are generally used to assemble complex equipment that requires quick repair or adjustment. Through their unique shape and surface finish, knurled wing screws can adapt to various application needs and ensure a secure connection.
Key Features
- Butterfly head design: The knurled wing screw features a unique butterfly-shaped head design, resembling a butterfly's wing, providing a larger gripping area for manual turning. This design facilitates operation, especially in confined spaces or areas where traditional tools are difficult to use.
- Knurling: The knurling on the screw head enhances grip and makes it easier to obtain stable friction during rotation, thus enabling tool-less tightening and loosening.
- High-strength design: Knurled wing screws are typically made of high-strength metal materials (such as carbon steel and stainless steel), possessing good durability and corrosion resistance. Even under high loads or high temperatures, the screws maintain their tightening performance, ensuring stable operation over extended periods.
