Klimas WF Self-Tapping Screw, 4.8 mm x 19 mm, RAL 6020, 250 pcs

The Klimas WF self-tapping screw, measuring 4.8 mm x 19 mm, is a professional-grade fastener engineered for robust metal-to-metal and metal-to-wood connections. Finished in a durable RAL 6020 green coating, these screws provide both structural integrity and a seamless aesthetic finish for roofing and cladding projects. Each pack contains 250 pieces, offering a reliable solution for various construction tasks requiring high corrosion resistance and long-term stability in outdoor environments.

Advantages

These self-tapping screws are designed for efficiency, featuring a sharp point that allows for quick penetration into metal surfaces without the need for pre-drilling in many applications. The galvanized coating provides an essential layer of protection against rust and environmental degradation, ensuring that the connection remains secure over time. The RAL 6020 color finish allows the fasteners to blend naturally with green-toned roofing materials, providing a clean and professional appearance for any installation.

Suitable for

• Roofing installations
• Metal cladding and siding
• General metal-to-metal construction
• Attaching metal sheets to wooden substructures

When it may not be suitable

This product is not intended for use in heavy-duty structural steel connections that require high-tensile bolts or specialized load-bearing anchors. It may also be unsuitable for applications involving highly corrosive chemical environments where specialized stainless steel fasteners are required.

Key specifications

• Diameter: 4.8 mm
• Length: 19 mm
• Finish: Galvanized with RAL 6020 coating
• Quantity: 250 pieces
• Application: Metal-to-metal and metal-to-wood

How to use

To achieve the best results, ensure the surface is clean and free of debris before installation. Use a power drill with the appropriate bit size to drive the screw perpendicularly into the material. Apply steady pressure until the screw head is flush with the surface, ensuring the washer creates a tight seal to prevent moisture ingress. Avoid over-tightening to maintain the integrity of the fastener and the surrounding material.

What to consider before purchase

• Verify the thickness of the metal being fastened to ensure the 19 mm length is sufficient.
• Confirm the color match with your specific roofing or cladding material.
• Ensure the drill bit used is compatible with the screw head type.

Usage recommendations

For optimal performance and longevity, always use a calibrated power tool to prevent stripping the threads and ensure the galvanized coating remains intact during the installation process.
