CSK Phillips Head Self Drilling Screws are designed for fast, efficient, and flush installation in metal-to-metal, wood-to-metal, and sheet metal applications. These screws combine a countersunk (CSK) head for a smooth finish with a Phillips cross-slot drive and a self-drilling tip that eliminates the need for pre-drilling, making them highly suitable for industrial construction, furniture, and panel assembly work.
Key Benefits
No pre-drilling required: The drill point enables direct installation, saving time and labor costs.
Flush finish: The CSK head allows the screw to sit flush with the surface, delivering a clean, snag-free look, ideal for visible surfaces in furniture or panels.
Corrosion-resistant options: Available in stainless steel and zinc-plated finishes for durability and weather resistance.
High durability: Manufactured from carbon steel or stainless steel, with heat-treated tips for strength and reliability in demanding environments.
Reduced mess and increased speed: By eliminating the need for separate pilot holes, installation is faster and cleaner on-site.
Typical Applications
Sheet metal fabrication: Commonly used for joining sheet metal panels together, especially in roofing, cladding, and ductwork.
Furniture assembly: Ideal for applications that require an aesthetic flush finish, such as cabinet doors, panels, or modular furniture.
Construction and building: Used for attaching wood to metal or securing lightweight steel sections in general construction and interior works.
Electrical and control panels: Employed where a flush finish and vibration resistance are essential.
Hardware fittings: Suitable for hinge assembly, bracket mounting, and securing hardware in windows, doors, and partition systems.
Usage & Installation Steps
Choose the appropriate size and material according to the application (e.g., stainless steel for outdoor or corrosive settings, carbon steel for general indoor use).
Position the screw at the intended fastening point and drive in with a Phillips screwdriver or bit; the self-drilling tip creates its own pilot hole and the screw forms its threads while fastening.
For soft materials, a washer may be used under the head to prevent it from embedding too deeply.
For maximum holding power, ensure the screw length is appropriate for the thickness of materials being joined.
Size Range
Diameter (Gauge): Typically from M3.5 (#6) up to M4.8 (#10), covering standard industry requirements.
Length: Available from 13 mm up to 100 mm or more, with common sizes including 4.8 x 25 mm, 4.8 x 50 mm, 4.8 x 65 mm, and 4.8 x 75 mm.
Standards: Manufactured to DIN 7504O and other specifications, ensuring quality and interchangeability.
