Pan Head Phillips Self-Tapping Screw (DIN 7981) is a self-tapping fastener that conforms to the DIN 7981 standard. It is widely used for joining materials like metal sheets, plastics, and wood. The screw has a round pan-shaped head with a Phillips drive slot on top, and its self-tapping threads enable it to cut threads directly into materials without the need for pre-tapped holes.
The DIN 7981 pan head Phillips self-tapping screw is a type of screw with the following characteristics:
Pan Head: The head is rounded with a smooth surface, providing a larger contact area, making it suitable for applications where a moderate load distribution is required.
Phillips Drive: The screw has a Phillips cross slot, making it compatible with standard Phillips screwdrivers for easy installation.
Self-Tapping Function: The sharp threads of the screw can directly cut into materials, eliminating the need for pre-drilled or pre-threaded holes.
Self-Tapping Capability:
No pre-drilling or thread preparation is required, enabling the screw to penetrate materials directly, saving time and effort.
Material Options:
Commonly made from carbon steel (with zinc plating for corrosion resistance) or stainless steel for strength and durability.
Pan Head Design:
The rounded head provides a clean and neat appearance, distributing pressure evenly and reducing the risk of material damage.
Ideal for applications where the screw head is visible after installation.
Ease of Installation:
The Phillips drive design ensures easy and efficient fastening using a standard screwdriver or power tool.
High Efficiency:
The self-tapping thread design simplifies installation, making it ideal for large-scale or rapid assembly.
Metal Sheet Connections:
Commonly used in sheet metal fabrication, electrical enclosures, and steel plate assembly.
Plastic Component Fastening:
Suitable for assembling and securing plastic housings and components.
Woodworking:
Ideal for joining wood or for wood-to-other-material connections where high load-bearing is not required.
Electrical Equipment:
Used in assembling control boxes, switch panels, and light fixtures.
Household Appliances:
Widely applied in home appliances and furniture assembly, such as securing washing machine and air conditioner housings.
Construction Assembly:
Used to fasten thin metal sheets, wall panels, or lightweight materials in building and construction projects.

Are these screws suitable for use with wood?
Although cross-slotted spherical cylindrical head screws are typically used in metal and plastic, they can also be used in softer woods. However, wood may not provide the same self-tapping characteristics as metals, so pre-drilling might be necessary for a secure connection.
What are the advantages of the spherical design?
The spherical head design helps to evenly distribute the pressure applied to the screw, reducing localized stress and preventing excessive friction between the screw and the material. This results in better durability and longevity. It also offers a smoother and more aesthetically pleasing appearance in some applications.
How do I choose the right cross-slotted spherical cylindrical head screw?
When choosing the screw, consider the application environment, load requirements, material, thread size, and surface treatment. For environments with high corrosion risk, screws made from stainless steel or with corrosion-resistant coatings are recommended.
