Cross flange self tapping screw is a fastener that combines convenient installation, high-strength fixation, and wide applicability. Its core characteristics and typical application scenarios can be summarized as follows:
1, Structural characteristics
1. Head design
Cross groove drive: The head is equipped with a standard cross groove, compatible with universal screwdrivers or power tools, easy to operate and anti slip.
Flange structure: The flange extends below the head to increase the contact area, disperse pressure, avoid deformation or tearing of thin plate materials, and improve anti loosening performance.
2. Thread design
Self tapping thread: With a sharp tip and a large thread angle, it can directly penetrate lightweight materials such as wood, plastic, and thin steel plates without the need for pre drilling, simplifying the installation process.
High strength material: Made of carbon steel (such as 4.8 grade, 8.8 grade) or stainless steel (such as 304, 316), with surface treatment (galvanized, nickel plated, Dacromet, etc.) to enhance corrosion resistance and adapt to outdoor or humid environments.
2, Core advantages
1. Efficient installation
One step in place: No need for drilling, tapping, or locking operations, simply screw in to complete the fixation, saving labor and time costs.
Strong universality: compatible with multiple tools (manual screwdriver, electric screwdriver), suitable for different work scenarios.
2. High stability
Flange anti loosening: The flange is tightly attached to the surface of the material, forming a large area of frictional resistance, effectively preventing loosening caused by vibration or external forces.
Self tapping thread locking: After the thread is embedded in the material, it forms a mechanical bite, further enhancing the connection strength.
3. Strong adaptability
Material compatibility: Suitable for lightweight materials such as wood, plastic, thin steel plates (thickness ≤ 3mm), aluminum alloys, etc., meeting the needs of various fields such as construction, furniture, electronic equipment, etc.
Environmental adaptability: Galvanized or stainless steel materials can resist oxidation and corrosion, extending their service life.
3, Typical application scenarios
1. Furniture manufacturing
Fixed components such as boards, drawer slides, hinges, etc., to avoid cracking problems caused by traditional screws.
2. Architectural decoration
Install ceiling keel, partition board, skirting board, etc., and ensure that the flange plate is flat to avoid deformation caused by uneven stress.
3. Electronic devices
Fixed circuit boards, casings, heat sinks, and other lightweight components to avoid poor contact caused by vibration.
4. Car maintenance
Temporarily fix plastic parts such as bumpers and interior panels, or urgently repair metal sheet metal (with the assistance of thin plates).
