## Long description

Knauf TB 3.5x35mm self-drilling screws are specialized fasteners engineered for the secure attachment of gypsum plasterboards to metal profiles. These screws are specifically designed to penetrate metal studs and tracks with a thickness of up to 2.0 mm without the need for pre-drilling. The high-quality steel construction and precise drill point ensure efficient installation, while the bugle head design allows the screw to sit flush with the surface of the board, providing a smooth finish ready for subsequent jointing and decoration.
Advantages
The primary benefit of these screws is their self-drilling capability, which significantly reduces installation time by eliminating the need for pilot holes in metal framing. The sharp drill point ensures a clean entry, preventing damage to the gypsum board and ensuring a tight, reliable connection between the board and the metal profile. With a durable finish and consistent manufacturing quality, these screws provide long-term stability for drywall partitions, wall linings, and ceiling systems, making them a preferred choice for professional contractors and DIY enthusiasts alike.
Suitable for
Fastening gypsum boards to metal profiles up to 2.0 mm thick
Drywall partition wall construction
Installation of suspended ceiling systems
Interior wall lining and cladding projects
These screws may not be suitable for fastening gypsum boards to timber frames, as the drill point is specifically optimized for metal. Additionally, they are not intended for use with metal profiles exceeding 2.0 mm in thickness, as the drill point may struggle to penetrate thicker steel, potentially leading to stripped threads or broken screws.
Key specifications
Diameter: 3.5 mm
Length: 35 mm
Point type: Self-drilling
Head type: Bugle head
Quantity: 1000 pieces
Application material: Metal profiles
To use these screws, ensure the gypsum board is held firmly against the metal profile. Using a power screwdriver with a depth-control nosepiece, drive the screw through the board and into the metal profile until the head is slightly recessed below the surface of the board. Avoid over-driving the screw, as this can damage the gypsum core and weaken the connection.
What to consider before purchase
Verify the thickness of your metal profiles to ensure they do not exceed 2.0 mm
Ensure your power tool is compatible with standard drywall screw bits
Calculate the total number of screws required based on the spacing of your metal studs
For optimal results, maintain a consistent screw spacing as recommended by the gypsum board manufacturer and ensure the screws are driven perpendicular to the surface of the board.
