Product Description
A Pan Head Self-Drilling Screw is a type of screw that is widely used in various applications, especially for fastening metal, steel, and composite materials. This screw has a self-drilling feature, meaning it can drill its own hole while being driven into a material, eliminating the need for pre-drilling. Here's an in-depth explanation based on your previous questions
Product Overview:
A Pan Head Self-Drilling Screw is designed with a pan-shaped head that has a wide, flat surface, making it ideal for applications that require a larger contact area. The self-drilling tip allows the screw to penetrate materials, such as metal sheets, without the need for a pilot hole. This feature makes it a highly efficient and time-saving fastening solution.

Specifications | |
Screw Diameter: | Common diameters include M6, M8, M10, but other sizes are available depending on the requirement. |
Screw Length: | It can vary depending on the thickness of the material being fastened, with standard lengths such as 20mm, 25mm, 30mm, and 40mm. |
Thread Type: | Typically, these screws come with double threads or single threads, which enhance their ability to grip into materials securely. |
Head Type: | The pan head has a flat, rounded surface that provides a larger bearing area, which helps to distribute the load evenly and reduce the chance of damage to the surface being fastened. |
Drilling Tail Length: | The self-drilling tip enables it to penetrate materials like metal sheets, with typical thicknesses ranging from 0.8mm to 6mm. |

Materials:
These screws are often made from carbon steel, alloy steel, or stainless steel, depending on the application and required strength.
Surface Treatment:
Galvanized

Mechanical Properties | |
Tensile Strength: | These screws typically have a tensile strength ranging from 800-1200 MPa, making them suitable for heavy-duty applications. |
Shear Strength: | The shear strength is generally 600-1000 MPa, which allows the screws to hold materials securely under shear forces. |
Hardness: | Core Hardness: Typically HRC 30-45, which ensures a good balance of strength and toughness. Surface Hardness: The surface can reach HRC 45-55, ensuring a durable finish and resistance to wear. |

Applications
The Pan Head Self-Drilling Screw is highly versatile and is used in a wide variety of industries. Common applications include:
- Metal Sheet Fastening: Ideal for fixing steel, aluminum, and other metal sheets in construction, automotive, and manufacturing.
- Sandwich Panels: Commonly used in roofing and wall systems that use composite sandwich panels.
- Metal Roofing and Cladding: Perfect for securing roofing materials due to its strong self-drilling ability and corrosion resistance.
- Industrial Equipment Installation: Used in machinery assembly where metal-to-metal connections are needed.
- Automotive: Used in automotive bodywork and structural assembly where a secure, lasting fastener is needed.
