Cross Recessed Pan Head Self-tapping Screw is a common fastener widely used in various fields such as construction, manufacturing and home DIY.
The head adopts a cross-shaped design, providing good grip and improving the efficiency of screwdriver use. Suitable for a wide range of Phillips shaped screwdrivers (such as PH2).
The threads of the self-tapping screws are designed to drill directly into materials (such as wood, plastic or metal), eliminating the need for pre-punched holes, saving time and labor.
Common materials include carbon steel, stainless steel and alloy materials, with good corrosion resistance and strength to adapt to different working environments.
Different lengths and diameters are available to meet different usage requirements.
Can be galvanized, chrome-plated or other anti-rust treatment to increase durability and prolong service life.
Application Areas:
Furniture assembly: commonly used for joining wood and synthetic materials in the assembly of home furnishings and furniture.
Construction: used in the fixing of various structures such as walls and floors to provide stability.
Electronic products: self-tapping nails are also used for fixing in the shells and components of some electronic products.
Motor vehicle maintenance: commonly used in the installation and repair of automobile and motorcycle parts.
