## Summary description

The Knauf TN drywall screw, size 3.5x35mm, is a specialized fastener designed for mounting gypsum plasterboards to metal profiles. Featuring a sharp point and a fine thread, it ensures secure and reliable fixation in interior construction projects. These screws are essential for professional drywall installation, providing high pull-out resistance and stability for wall and ceiling systems.

## Long description

The Knauf TN drywall screw, measuring 3.5x35mm, is a high-quality fastener specifically engineered for the efficient installation of gypsum plasterboards onto metal profiles. These screws are a fundamental component in modern interior construction, ensuring that drywall panels are securely attached to metal framing systems. With a precision-engineered sharp point and a fine thread design, they allow for rapid penetration and firm anchoring, which is critical for maintaining the structural integrity of walls and ceilings.
Advantages
The primary benefit of using Knauf TN screws lies in their specialized design which minimizes the risk of damaging the plasterboard surface during installation. The fine thread provides excellent grip within metal profiles, significantly reducing the likelihood of the screw backing out over time. Furthermore, the high-quality steel construction ensures durability and resistance to shearing, providing a reliable connection that meets professional building standards for stability and safety in residential and commercial drywall applications.
Suitable for
Mounting gypsum plasterboards to metal profiles
Interior wall partition construction
Suspended ceiling installations
Professional drywall finishing projects
When it may not be suitable
These screws are specifically designed for use with metal profiles and may not provide optimal holding power when used with timber or wooden studs. For wood-based framing, a coarse-thread screw is typically recommended to ensure proper engagement with the material.
Key specifications
Length: 35 mm
Diameter: 3.5 mm
Material compatibility: Metal profiles
Quantity: 1000 pieces
How to use
To achieve the best results, use a power screwdriver equipped with a depth-limiting nose piece. Position the plasterboard against the metal profile and drive the screw through the board until the head is slightly recessed below the surface of the paper, without breaking the gypsum core. Ensure the screw is driven perpendicular to the surface to maintain maximum holding strength.
What to consider before purchase
Verify the thickness of the metal profiles to ensure the 35mm length is appropriate for your specific wall system.
Confirm the total number of screws required for your project area to ensure the 1000-piece pack is sufficient.
Ensure you have a compatible screwdriver bit for the screw head type.
Usage recommendations
For optimal structural performance, space the screws at regular intervals as specified by the manufacturer's installation guidelines for the particular plasterboard type being used.
