Product information

Description

Knauf TN25 drywall screws, measuring 3.5x25mm, are precision-engineered fasteners specifically designed for the reliable attachment of gypsum boards to metal profiles. These screws are a fundamental component in professional interior construction, providing a secure and durable connection for wall and ceiling systems. With their sharp point and specialized thread design, they facilitate quick penetration and firm anchoring, ensuring that drywall panels remain stable and properly aligned throughout the life of the structure.

Advantages

The primary benefit of using Knauf TN25 screws lies in their optimized design for metal framing. The sharp point allows for immediate engagement with the metal profile, significantly reducing installation time and preventing the screw from slipping during the initial drive. The fine thread is specifically calibrated to grip metal studs effectively, providing high pull-out resistance and a flush finish that is ideal for subsequent taping and jointing processes. These fasteners are manufactured to meet rigorous quality standards, ensuring consistent performance across large-scale construction projects.

Suitable for

  • Mounting gypsum boards to metal profiles
  • Interior wall partition construction
  • Suspended ceiling installations
  • Drywall lining systems

When it may not be suitable

These screws are not intended for use with wooden framing, as the fine thread design is optimized specifically for metal profiles. They are also not suitable for heavy-duty structural applications or outdoor environments where high corrosion resistance is required, as they are designed for standard interior drywall systems.

Key specifications

  • Length: 25 mm
  • Diameter: 3.5 mm
  • Material compatibility: Metal profiles
  • Standard: DIN 7504P
  • Quantity: 1000 pieces

How to use

To install, position the gypsum board firmly against the metal profile. Using a power screwdriver equipped with a depth-limiting nosepiece, drive the screw through the board and into the metal stud. Ensure the screw head is driven slightly below the surface of the board to allow for proper finishing, but avoid breaking the paper surface of the gypsum board, as this can compromise the holding strength.

What to consider before purchase

  • Verify the thickness of your metal profiles to ensure the 25mm length is appropriate for your specific wall system.
  • Ensure you have a compatible screwdriver bit for the screw head type.
  • Calculate the total number of screws required based on the spacing recommendations for your drywall installation.

Usage recommendations

For optimal results, maintain a consistent screw spacing as specified by the drywall manufacturer and ensure the screwdriver is set to the correct depth to prevent damage to the gypsum board core.
