Cross pan head triangle teeth self-locking screws, as defined by the GB6560 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 pan 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.

These screws are usually made of stainless steel, carbon steel, or other metallic materials. Surface treatments may include zinc plating, nickel plating, passivation, etc. to improve corrosion and wear resistance. The chemical composition of the stainless steel material should be within the range specified in the steel group, the chemical composition of A2 and A4 stainless steel is specified in the following table . 

Advantage:

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

Pan Head Design: The pan head offers a large bearing surface, which helps prevent the material from sinking or cracking, especially in softer materials.

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

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.

Machine and Equipment Assembly: In machinery and equipment assembly where a strong connection is needed, and the screw head should not protrude.
