Knauf Drywall Screws for Metal Profiles 3.5x35mm

Knauf Drywall Screws for Metal Profiles 3.5x35mm are professional-grade fasteners engineered for the secure attachment of gypsum boards to metal framing systems. These screws are manufactured to meet high quality standards, ensuring that your interior wall and ceiling installations remain stable and durable over time. With a precise 3.5mm diameter and 35mm length, they provide optimal holding power for standard drywall applications in both residential and commercial construction projects.

Advantages

The primary benefit of these Knauf screws is their specialized design, which facilitates rapid and efficient installation into metal profiles. The sharp point allows for immediate engagement with the metal surface, minimizing the risk of slippage during the fastening process. Furthermore, the thread geometry is optimized to pull the gypsum board tightly against the metal stud, creating a flush finish that is essential for high-quality surface preparation and subsequent finishing work such as taping and painting.

Suitable for

• Fastening gypsum boards to metal wall studs
• Installing drywall on metal ceiling grid systems
• Interior renovation and partition wall construction
• Securing plasterboard in residential and commercial buildings

When it may not be suitable

These screws are specifically optimized for use with metal profiles and may not provide the necessary grip when used with wooden framing. Additionally, they are not intended for structural load-bearing applications or for fastening materials to concrete or masonry surfaces.

Key specifications

• Diameter: 3.5 mm
• Length: 35 mm
• Material compatibility: Metal profiles
• Quantity: 200 pieces
• Standard: DIN 7504P

How to use

To achieve the best results, use a power screwdriver with a depth-limiting nose piece to prevent the screw head from penetrating too deeply into the gypsum board. Position the screw perpendicular to the metal profile and drive it in until the head is slightly recessed below the surface of the board. Ensure that the metal profile is properly aligned and secured before beginning the fastening process to maintain the integrity of the wall or ceiling structure.

What to consider before purchase

• Verify the thickness of your metal profiles to ensure the 35mm length is appropriate
• Calculate the total number of screws required based on the spacing of your metal studs
• Ensure you have a compatible screwdriver bit for the screw head type

Usage recommendations

For optimal structural integrity, space the screws at regular intervals along the metal profile, typically every 20 to 30 centimeters, depending on the specific requirements of your drywall system and local building regulations.
