Klimas WF Self-Tapping Screw, RAL3009, 4.8 mm x 19 mm, 250 pcs

The Klimas WF self-tapping screw is a professional-grade fastener engineered for reliable metal-to-metal and metal-to-timber connections. Measuring 4.8 mm in diameter and 19 mm in length, these screws are finished in a durable RAL3009 oxide red coating, ensuring both long-term corrosion resistance and seamless aesthetic integration with matching roofing or cladding materials. Each package contains 250 pieces, providing a sufficient supply for medium-to-large scale construction projects.

Advantages

These self-tapping screws offer exceptional structural integrity due to their high-quality galvanized steel construction, which is further protected by a specialized color coating. The design allows for efficient penetration into metal surfaces, reducing the need for pre-drilling and significantly speeding up installation times. The RAL3009 finish is specifically formulated to withstand environmental exposure, preventing rust and maintaining its appearance over many years of service.

Suitable for

• Roofing installations
• Wall cladding systems
• Metal sheet fastening
• General metal-to-timber construction

When it may not be suitable

These screws are not intended for use in masonry or concrete applications, as they lack the necessary thread design for such materials. Additionally, they may not be suitable for high-load structural steel connections where specific bolt-grade requirements are mandated by building codes.

Key specifications

• Diameter: 4.8 mm
• Length: 19 mm
• Finish: Galvanized with RAL3009 oxide red coating
• Quantity: 250 pieces
• Application: Metal-to-metal and metal-to-timber

How to use

To achieve the best results, use a power drill with an appropriate bit size to ensure a secure fit without stripping the screw head. Position the screw perpendicular to the surface and apply steady pressure while driving it into the material. Ensure the screw is tightened until the washer is firmly seated against the surface to create a weather-tight seal.

What to consider before purchase

• Verify the thickness of the metal sheets to ensure the 19 mm length is sufficient.
• Check that the RAL3009 color matches your existing roofing or cladding panels.
• Ensure you have the correct driver bit for the screw head type.

Usage recommendations: Always wear appropriate safety gear, including eye protection, when installing fasteners. Avoid over-tightening to prevent damage to the protective coating or the material surface.
