Klimas WDD Self-Tapping Screw, 4.8 mm x 35 mm, RAL 8017, 250 pcs

The Klimas WDD self-tapping screw is a professional-grade fastener engineered for secure and efficient metal-to-metal or metal-to-timber mounting. Measuring 4.8 mm in diameter and 35 mm in length, this screw features a specialized design that allows for direct drilling into surfaces without the need for pre-drilling. Finished in RAL 8017, it provides an aesthetic, color-matched solution for exterior installations where visual integration is essential. Each package contains 250 pieces, ensuring a sufficient supply for medium-to-large scale construction and renovation tasks.

Advantages

The primary benefit of the Klimas WDD screw lies in its robust construction and high-quality galvanized coating, which provides enhanced resistance to environmental factors and corrosion. Its self-tapping capability significantly reduces installation time and labor costs by eliminating the need for pilot holes. The precise thread geometry ensures a firm grip and high pull-out resistance, while the color-matched head blends seamlessly with standard brown roofing and cladding materials, maintaining a clean and professional finish.

Suitable for

• Fastening metal sheets to wooden or metal substructures
• Installation of roofing and facade elements
• Exterior construction projects requiring color-coordinated fasteners
• General renovation and repair work involving metal components

When it may not be suitable

This screw is specifically designed for metal and wood applications and may not be suitable for masonry, concrete, or soft materials like drywall where specialized anchors are required. It should not be used in highly corrosive environments, such as coastal areas with high salt exposure, without additional protective measures.

Key specifications

• Diameter: 4.8 mm
• Length: 35 mm
• Finish: Galvanized with RAL 8017 coating
• Quantity: 250 pieces
• Application: Metal and wood surfaces

How to use

To achieve the best results, use a power drill or screwdriver with an appropriate bit size that matches the screw head. Position the screw perpendicular to the surface to ensure a straight entry. Apply steady pressure while driving the screw into the material until the head is flush with the surface. Avoid over-tightening to prevent damage to the material or the screw thread.

What to consider before purchase

• Verify the thickness of the material to ensure the 35 mm length is sufficient for a secure hold
• Check the compatibility of the RAL 8017 color with your specific project materials
• Ensure the power tool used has adjustable torque settings to prevent stripping

Usage recommendations: Always wear appropriate personal protective equipment during installation. For optimal performance in outdoor conditions, ensure the screw head is properly seated to maintain the integrity of the connection and prevent water ingress.
