Klimas WDD Self-Tapping Screw, 4.8 mm x 35 mm, RAL 7024, 250 pcs

The Klimas WDD self-tapping screw is a professional-grade fastener engineered for secure and efficient metal-to-metal or metal-to-substrate connections. With a diameter of 4.8 mm and a length of 35 mm, this screw is designed to provide optimal holding power in various construction and assembly tasks. The surface is finished in a durable RAL 7024 graphite grey coating, which provides both corrosion resistance and a clean, aesthetically pleasing appearance that blends seamlessly with dark-colored metal surfaces.

Advantages

These self-tapping screws offer exceptional performance due to their specialized design that allows for quick penetration into metal materials without the need for pre-drilling in many applications. The high-quality galvanized coating ensures long-term protection against environmental factors, preventing rust and degradation over time. The precise dimensions and color-matched head make these screws an excellent choice for projects where both structural integrity and visual consistency are required.

Suitable for

• Fastening metal sheets to metal profiles
• Assembly of metal structures and frames
• Installation of dark-colored metal cladding
• General construction and renovation projects

When it may not be suitable

This product is specifically designed for metal applications and may not provide adequate holding power in soft materials like wood or drywall. It is also not recommended for use in highly corrosive environments, such as direct contact with saltwater or industrial chemicals, where specialized stainless steel fasteners would be required.

Key specifications

• Diameter: 4.8 mm
• Length: 35 mm
• Finish: Galvanized with RAL 7024 graphite grey coating
• Material compatibility: Metal
• Quantity: 250 pieces per pack

How to use

To achieve the best results, ensure that the surface is clean and free of debris before installation. Use a power drill or screwdriver with the appropriate bit size to drive the screw into the material. Apply steady, consistent pressure to allow the self-tapping tip to engage with the metal surface. Avoid over-tightening to prevent stripping the threads or damaging the protective coating of the screw head.

What to consider before purchase

• Verify the thickness of the metal material to ensure the 35 mm length is sufficient.
• Confirm that the RAL 7024 color matches your specific project requirements.
• Ensure you have the correct drive bit size for the screw head.

Usage recommendations

For optimal structural performance, always ensure the screw is driven perpendicular to the surface. If working with thicker metal gauges, consider performing a test installation to determine if a pilot hole is necessary for your specific application.
