Klimas WF Self-Tapping Screw, RAL8004, 4.8 mm x 19 mm, 250 pcs

The Klimas WF self-tapping screw is a professional-grade fastener engineered for secure and durable connections in metal-to-metal or metal-to-wood applications. Measuring 4.8 mm in diameter and 19 mm in length, this screw features a specialized RAL8004 color finish, which provides both an aesthetic match for specific roofing or cladding materials and enhanced resistance against environmental factors. Each pack contains 250 pieces, ensuring a reliable supply for construction projects that demand precision, structural integrity, and long-lasting performance.

Advantages

The primary benefit of the Klimas WF self-tapping screw lies in its high-quality galvanized coating, which offers superior protection against corrosion and oxidation, extending the lifespan of the connection even in challenging weather conditions. The self-tapping design allows for efficient installation without the need for pre-drilling in many materials, significantly reducing labor time and increasing productivity on the job site. Furthermore, the color-matched finish ensures a seamless and professional appearance, making it an ideal choice for visible exterior installations where aesthetics are as important as mechanical strength.

Suitable for

• Roofing installations and repairs
• Attaching metal sheets to wooden or metal substructures
• General construction and assembly tasks
• Exterior cladding and facade mounting

When it may not be suitable

This screw may not be suitable for applications involving extremely thick steel profiles where the self-tapping point cannot penetrate effectively without pre-drilling. It is also not recommended for use in highly corrosive environments, such as coastal areas with high salt exposure, where specialized stainless steel fasteners might be required.

Key specifications

• Diameter: 4.8 mm
• Length: 19 mm
• Finish: Galvanized with RAL8004 color coating
• Material compatibility: Metal and wood
• 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 with an appropriate bit size to drive the screw perpendicularly into the material. Apply steady, controlled pressure to allow the self-tapping point to engage with the surface. Avoid over-tightening to prevent damage to the material or the screw head, ensuring a firm and secure fit that maintains the integrity of the seal.

What to consider before purchase

• Verify the thickness of the material to ensure the 19 mm length is sufficient for a secure grip.
• Confirm that the RAL8004 color matches your specific project requirements.
• Check the compatibility of the screw point with the hardness of the metal substrate.

Usage recommendations

For optimal performance and to maintain the integrity of the protective coating, always use the correct torque settings on your power tools and ensure the screw is driven straight into the material.
