Features
The screw head is characterized by a rounded, low-profile shape similar to a button head screw. This design allows for a smooth, flush fit when installed.
Unlike standard button head screws, a flange is integrated under the head. The flange provides a wider bearing surface that distributes the load and increases the clamping force when the screw is tightened.
Typically features a hex socket (Allen key) drive, which allows for secure tightening with a tool.
Materials
Steel: Commonly used for general applications, often available with various coatings (e.g., zinc-plated, black oxide) for corrosion resistance.
Stainless Steel: Offers excellent corrosion resistance, suitable for outdoor or marine environments.
Alloy Steel: Provides high strength and durability for demanding applications.
Other Materials: Including brass and nylon for specific requirements like electrical insulation or decorative purposes.
Applications
Mechanical Assemblies: Used in machinery, equipment, and automotive applications where a flush mounting surface is desired along with secure clamping.
Construction: Utilized in building and construction projects where appearance and functionality are important.
Electronics: Common in electronic enclosures and paneling where a low-profile screw head is necessary for aesthetic or functional reasons.
Furniture: Used in furniture assembly for securing components while maintaining a clean and neat appearance.
Advantages
Low Profile: The button head design provides a flush finish when installed, enhancing the appearance of the surface.
Increased Clamping Force: The integrated flange increases the contact area and clamping force, providing a more secure fastening.
Corrosion Resistance: Available in materials like stainless steel that offer excellent resistance to corrosion, ensuring longevity in harsh environments.
