A Pan Head Self-Drilling Screw is a self-drilling and self-tapping fastener with a rounded pan-style head.
The screw is designed to drill through suitable material and create its own mating thread during installation.
The pan head provides a conventional rounded head profile and is commonly selected for general fastening applications where a larger and more visible head than a countersunk screw is acceptable.
Main Features of Pan Head Self-Drilling Screws
Pan Head Design
The Pan Head is the defining feature of this screw.
It provides a rounded head profile with a relatively broad bearing surface compared with a countersunk screw.
This makes it suitable for applications where the screw head remains above the surface rather than being recessed.
Self-Drilling and Self-Tapping
Pan Head Self-Drilling Screws combine:
Drilling + Thread Forming + Fastening
into one installation process.
This can improve installation efficiency when used with suitable materials and thicknesses.
Suitable for Light Sheet Metal Assembly
Pan Head Self-Drilling Screws are mainly intended for light sheet metal assembly.
They can be used for suitable:
- Sheet metal
- Metal panels
- Thin-gauge metal
- Building components
- Light metal assembly
Pan Head Self-Drilling Screws for Indoor Panel Assembly
Pan Head Self-Drilling Screws can be used for indoor panel and board assembly where a conventional rounded screw head is acceptable.
They may be selected for:
- Interior panels
- Light metal panels
- Board assembly
- Home decoration
- General construction components
For applications requiring a watertight seal, a suitable EPDM washer can be added according to the application.
Pan Head Self-Drilling Screws for Roofing Applications
When Pan Head Self-Drilling Screws are used for exterior roofing or cladding applications, the screw can be combined with an appropriate sealing washer.
For example:
Pan Head SDS + EPDM Steel Bonded Washer
can provide a screw-and-washer assembly for applications where both fastening and sealing are required.
The washer configuration should be selected according to the roofing material, panel profile, environmental exposure, and sealing requirements.
Stainless Steel Pan Head Self-Drilling Screws
Although the main product entity is Pan Head Self-Drilling Screw, stainless steel is an important material option.
Available stainless steel grades include:
- Stainless Steel 304
- Stainless Steel 316
- Stainless Steel 410
Stainless Steel 304
Suitable for general corrosion-resistant applications.
Stainless Steel 316
Often selected for more demanding environments, particularly where chloride or salt exposure is a concern.
Stainless Steel 410
Can be considered when higher hardness is required.
The appropriate stainless steel grade should always be selected according to the application environment and mechanical requirements.

SELF DRILLING SCREWS
Self drilling screws are very easy to install, but con- tractors still encounter challenges like penetration speed or functioning problems. Therefore, it is our goal to eradicate those challenges by making self-drilling screws that are faster at drilling and are more stabilized.
Easy to use
SEC's Nick Point self-drilling tip contains a small indent slightly on the side of the screw tip. It has been verified through many experiments and comparisons to have a consist shorter drilling time. Furthermore, our feedback from construction staffs indicating an effortless quick drilling speed.
Stable quality
Our self-drilling screws have a better penetration point that is slip resistant. Besides, a single SEC self-drilling screw can be redrilled 5 times without affecting performance.
Suitable coating
Depending on the environment at which your self-drilling screws are applied, we are able to coat these products according to C1-C4 specifications or according to your own customized specifications.own customized specifications.
Any customization
The SEC self-drilling screw can be matched with any EPDM size or steel bonded washer. We can also paint the screw head to the color of your roof or wall.Common Applications
