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.
