## Long description

Knauf XTN self-tapping screws 3.9x38mm are high-performance fasteners specifically engineered for the professional installation of gypsum boards onto metal profiles. These screws are essential components in drywall construction, ensuring a secure and durable connection between the plasterboard and the underlying metal framework. With a precise 3.9mm diameter and 38mm length, they provide optimal grip and stability for various interior finishing projects.
Advantages
The primary advantage of these screws lies in their specialized design, which allows for rapid and efficient penetration into metal profiles without the need for pre-drilling. The galvanized coating provides excellent resistance against corrosion, ensuring the longevity of the installation in standard indoor environments. Their sharp point and optimized thread profile minimize damage to the gypsum board surface while maximizing holding power, resulting in a clean and reliable finish for partition walls and ceiling systems.
Suitable for
Installation of gypsum boards to metal profiles
Construction of partition walls
Interior finishing and ceiling assembly
Professional drywall installation projects
When it may not be suitable
These screws are specifically designed for use with metal profiles and may not provide adequate holding power when used with wooden studs or masonry. They are not intended for heavy-duty structural applications where high load-bearing capacity is required beyond standard drywall systems.
Key specifications
Diameter: 3.9 mm
Length: 38 mm
Material: Galvanized steel
Quantity: 1000 pieces per pack
Application: Metal profiles
How to use
To use the Knauf XTN screws, position the gypsum board firmly against the metal profile. Using a power screwdriver with a depth-limiting attachment, drive the screw through the board and into the metal profile until the head is slightly recessed below the surface of the board. Ensure the screw is driven perpendicular to the surface to maintain structural integrity.
What to consider before purchase
Verify the thickness of the metal profiles to ensure the 38mm length is appropriate
Ensure the quantity of 1000 pieces is sufficient for the scale of your project
Confirm compatibility with your specific drywall system requirements
Usage recommendations
For the best results, use a professional screwdriver with a depth stop to prevent over-driving the screw, which could damage the gypsum core and compromise the holding strength.
