Plum pan head triangle teeth self-locking screws, as referenced by GB6561, are a specialized 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. 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.

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.

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.

Aerospace and Marine: For lightweight and high-strength connections in aerospace and marine applications where corrosion resistance is also a factor.
