Description
The Cross Countersunk Head Screw is a precision-engineered machine screw designed for applications requiring a flush, smooth surface finish. Manufactured to GB819 standards from high-quality 304 stainless steel, this fastener offers excellent corrosion resistance, durability, and strength. Its countersunk head shape ensures that the screw sits flush with the surface after installation, delivering both functionality and a clean aesthetic. The cross recessed drive (Phillips) allows easy installation with secure torque transfer, minimizing the risk of slipping. These screws are widely utilized in electronics, machinery, furniture assembly, and other applications where a clean, flush aesthetic and reliable fastening are essential.
Features & Benefits
- Flush Finish: The countersunk head shape is specifically designed to fit into a pre-drilled, conical hole, allowing it to sit completely flush with the surface. This is perfect for applications requiring a smooth, non-protruding finish for safety or aesthetics.
- Corrosion & Rust Resistance: Manufactured from high-quality 304 stainless steel, these screws offer superior resistance to rust and corrosion in humid or demanding environments.
- Secure & Stable: The cross-recessed (Phillips) drive ensures easy installation and a tight lock, while the deep, uniform threading provides even force distribution for a secure connection without slippage.
- Versatile Application: This screw is ideal for a wide range of uses, including furniture assembly, electronics, machinery, and other applications where a clean, flush appearance and reliable fastening are critical.
