Pan head self drilling screws, also called round head self drilling screws, have a disc-shaped head with a large contact area. They can evenly distribute pressure during installation, reduce pressure on the material, and maintain a smooth appearance of the material.
Note: The length of the pan head self drilling screw does not include the length of the head.

PAN Head Self-drilling Screws - Precision Fastening for Metal-to-Metal and Metal-to-Wood Applications
Product Features
- Integrated Drill Point: Designed to create its own pilot hole, enabling consistent penetration through metal sheets and reducing installation time.
- PAN Head Structure: Provides a broad bearing surface that enhances load distribution and supports stable fastening in structural and equipment assemblies.
- Surface Treatment Options: Available with zinc plating, Ruspert coating, or other protective finishes to support corrosion resistance in varied environments.
Product Description
PAN head self-drilling screws are manufactured according to common industrial fastening standards such as ISO, DIN, and ASTM. The screw geometry, including the self-drilling point and PAN head profile, supports controlled installation torque and stable engagement with metal substrates. Material selections typically include carbon steel or stainless steel to meet structural, environmental, and durability requirements. These screws are widely used in applications requiring metal-to-metal fastening, sheet metal assembly, and light-gauge steel construction.
Application Fields
This product is suitable for the following scenarios:
- Metal-to-metal fastening in HVAC ducts, steel framing, and mechanical assemblies
- Installation of thin-gauge steel panels or aluminum sheets
- Wood-to-metal attachment in construction and interior fixing projects
- Appliance manufacturing and general industrial equipment assembly
FAQ
1. How do PAN head self-drilling screws compare with standard self-tapping screws in metal applications?
PAN head self-drilling screws include a drill point that eliminates the need for pre-drilling, which helps maintain installation efficiency in metal fabrication and sheet metal assembly. In contrast, standard self-tapping screws require a pre-made pilot hole. For applications involving repeated fastening on thin metal sheets or structural steel, self-drilling designs support more consistent performance.
2. What factors affect the durability of PAN head self-drilling screws in outdoor or humid environments?
The durability is influenced by material type, coating selection, and environmental exposure. Stainless steel versions are commonly used in high-humidity or chemical-exposure environments due to their corrosion-resistant properties. Carbon steel screws with zinc or Ruspert coatings provide protective layers for general construction and industrial use. Choosing the correct combination based on site conditions helps support stable long-term fastening performance.
3. Can PAN head self-drilling screws be used for both metal and wood substrates?
Yes, these screws can be applied in mixed-material fastening scenarios. When used for wood-to-metal installation, coarse thread versions support stronger engagement with wood fibers, while the drill point ensures clean penetration through metal layers. Selecting the proper thread geometry is essential to achieve reliable fastening in composite assemblies.
