Product information

Description

Knauf LN 3.5x11mm self-tapping screws are professional-grade fasteners specifically engineered for the secure assembly of metal profiles in drywall construction systems. These high-quality screws are designed to provide a robust and stable connection between metal components, ensuring the structural integrity of wall and ceiling framing. Manufactured to meet rigorous standards, these fasteners are an essential component for achieving precise and durable interior finishing results.

Advantages

The primary advantage of these Knauf screws lies in their specialized design, which allows for efficient penetration and fastening into metal profiles without the need for pre-drilling. Their high-quality construction ensures resistance to shearing and loosening, providing long-term stability for complex framing structures. By utilizing these dedicated fasteners, installers can achieve consistent performance and reliable connections that meet professional building requirements for drywall systems.

Suitable for

  • Connecting metal profiles in drywall partition walls
  • Assembling metal ceiling grid systems
  • Fastening metal components in interior construction
  • Professional drywall framing projects

When it may not be suitable

These screws are specifically optimized for metal-to-metal connections and are not intended for fastening drywall boards to metal profiles or for use with wood substrates. They may not provide adequate holding power in materials other than the specified metal profiles.

Key specifications

  • Diameter: 3.5 mm
  • Length: 11 mm
  • Material application: Metal
  • Standard: DIN 7504P
  • Quantity: 1000 pieces

How to use

To use these screws, ensure that the metal profiles are correctly aligned and positioned according to the construction plan. Use a power screwdriver with a suitable bit to drive the screw through the overlapping metal profiles. The self-tapping tip is designed to pierce the metal efficiently; apply steady pressure until the screw head is flush with the surface of the profile. Avoid over-tightening to maintain the integrity of the metal connection.

What to consider before purchase

  • Verify the thickness of the metal profiles to ensure compatibility with the screw length
  • Ensure the use of a compatible screwdriver bit to prevent damage to the screw head
  • Calculate the total number of connections required for your project to ensure sufficient quantity

Usage recommendations

For optimal results, use a professional-grade electric or battery-powered screwdriver with adjustable torque settings to prevent stripping the metal or damaging the screw head during installation.
