Klimas WFD Self-Tapping Screw, 4.8 mm x 25 mm, RAL 8017, 250 pcs

The Klimas WFD self-tapping screw is a professional-grade fastener engineered for efficient and secure metal-to-metal or metal-to-timber fastening applications. With a diameter of 4.8 mm and a length of 25 mm, this screw is designed to provide a strong hold while maintaining structural integrity. The RAL 8017 chocolate brown finish ensures that the fastener blends seamlessly with matching surfaces, making it an ideal choice for visible installations where aesthetics are as important as mechanical performance.

Advantages

These self-tapping screws offer exceptional durability due to their galvanized coating, which provides reliable resistance against corrosion and environmental wear. The precision-engineered thread design allows for rapid installation without the need for pre-drilling in many applications, significantly reducing assembly time. The color-matched finish eliminates the need for additional paint or covers, ensuring a clean and professional appearance for your construction or renovation projects.

Suitable for

• Fastening metal sheets to metal frameworks
• Attaching metal components to wooden structures
• Roofing and cladding installations requiring color-matched hardware
• General assembly tasks in construction where a brown finish is required

When it may not be suitable

This screw is not intended for use in masonry, concrete, or heavy-duty structural steel connections where specialized anchors are required. It may also be unsuitable for environments with extreme chemical exposure where stainless steel fasteners are strictly mandated.

Key specifications

• Diameter: 4.8 mm
• Length: 25 mm
• Finish: Galvanized with RAL 8017 coating
• Quantity: 250 pieces
• Application: Metal fastening

How to use

To achieve the best results, use a power drill or screwdriver equipped with the appropriate bit size. Position the screw perpendicular to the surface and apply steady pressure while driving it into the material. Ensure the drill speed is controlled to prevent stripping the thread or damaging the surface finish. For optimal holding power, ensure the screw is driven until the washer is firmly seated against the surface.

What to consider before purchase

• Verify the thickness of the material to ensure the 25 mm length is sufficient for your specific application
• Confirm that the RAL 8017 color matches your existing surface requirements
• Ensure you have the correct drive bit compatible with the screw head type

Usage recommendations

For long-lasting results, avoid over-tightening the screws, as this can compromise the seal and the integrity of the galvanized coating. Always store the remaining screws in a dry environment to prevent premature oxidation.
