Cross countersunk triangular teeth self-locking screws conforming to the GB6561 standard are a type of self-tapping screw designed for high clamping force and resistance to loosening, especially in applications where vibration is present. These screws are characterized by their countersunk head, which provides a large bearing surface, and their self-locking feature, which ensures a secure connection without the need for additional locking components like nuts or washers. The triangular teeth on the threads offer a strong grip and resistance to loosening.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

Self-Locking Feature: The triangular teeth on the threads provide a mechanical lock that resists loosening due to vibration or dynamic loads.

Countersunk Head Design: The countersunk head offers a large bearing surface, which helps prevent the material from sinking or cracking, especially in softer materials. It also allows for a flush finish with the surface being fastened.

High Tensile Strength: Made from high-strength materials like carbon steel or stainless steel, these screws offer reliable strength and durability.

Versatility: Suitable for a wide range of materials, including metals, plastics, and composites, making them a versatile choice for various industries.

Efficiency: Reduces assembly time by combining drilling and tapping operations into one step, increasing productivity.

Scope of Application

Automotive Industry: Used in applications where high torque and vibration resistance are required, such as in engine assemblies or suspension systems.

Construction and HVAC: Ideal for fastening metal roofing, wall paneling, and ductwork where a strong connection without pre-drilling is needed.

Electrical and Electronics: Secures components in electrical enclosures and control panels, as well as in the assembly of electronic devices where a low-profile appearance is desired.

Furniture and Cabinetry: Assembles wooden or composite materials in furniture and cabinetry, providing a secure and durable connection with a neat appearance.

Signage and Display: Used in the assembly of signs and displays where a flush finish is important for a clean look.
