The Klimas WFD self-tapping screw is a professional-grade fastener engineered for secure and efficient metal-to-metal or metal-to-substrate assembly. With a diameter of 4.8 mm and a length of 25 mm, these screws are designed to provide a firm grip and long-lasting stability. The RAL 9005 black finish ensures that the fasteners blend seamlessly into dark-colored surfaces, providing a clean and professional aesthetic for any project.
Advantages
These self-tapping screws offer exceptional durability due to their high-quality galvanized coating, which provides reliable resistance against corrosion and environmental wear. The precision-engineered thread design allows for quick and easy penetration into metal surfaces, significantly reducing installation time and effort. By choosing this fastener, you ensure a robust connection that maintains its integrity under various mechanical stresses, while the black finish eliminates the need for additional painting or masking.
Suitable for
- Fastening metal sheets to metal frames
- General construction and assembly tasks
- Projects requiring a discreet, black-finished fastener
- Industrial and residential metal installations
This product may not be suitable for applications involving non-metallic materials like wood or masonry, as the thread geometry is specifically optimized for metal substrates. Additionally, it should not be used in environments with extreme chemical exposure where specialized stainless steel fasteners would be required to prevent degradation.
Key specifications
- Diameter: 4.8 mm
- Length: 25 mm
- Finish: Galvanized with RAL 9005 black coating
- Quantity: 250 pieces per pack
- Application: Metal surfaces
To use these screws effectively, ensure that the surface is clean and free of debris. Use a power drill with the appropriate bit size to drive the screw directly into the metal. The self-tapping tip is designed to create its own pilot hole, but for thicker metal gauges, pre-drilling may be recommended to ensure optimal alignment and to prevent surface damage.
What to consider before purchase
- Verify the thickness of the metal material to ensure the 25 mm length is sufficient
- Confirm that the RAL 9005 black color matches your specific installation requirements
- Ensure you have the correct drive bit compatible with the screw head type
For the best results, maintain a consistent pressure and speed during installation to avoid stripping the screw head or damaging the metal surface. Always store the screws in a dry environment to preserve the integrity of the galvanized coating.
