Koelner FS-3545 Drywall and Profile Screws 3.5x45mm, 500 pieces

The Koelner FS-3545 drywall and profile screws are professional-grade fasteners engineered for the secure attachment of gypsum boards to metal or wooden framing systems. Measuring 3.5x45mm, these screws are specifically designed to provide a firm grip and long-lasting stability in various interior construction applications. Each package contains 500 pieces, making it a practical choice for both small-scale renovations and larger professional building projects.

Advantages

These screws are manufactured from high-quality steel, ensuring excellent resistance to snapping and bending during installation. The sharp point allows for quick penetration into both metal profiles and wooden studs, reducing the time required for mounting. The specialized head design ensures that the screw sits flush with the surface of the drywall, creating a smooth finish that is easy to cover with joint compound and paint. Their reliable performance minimizes the risk of board movement, contributing to the overall structural integrity of partition walls and ceilings.

Suitable for

• Mounting gypsum boards to metal profiles
• Attaching drywall to wooden frames
• Interior partition wall assembly
• Ceiling finishing and suspended ceiling installations
• General interior renovation and construction tasks

When it may not be suitable

These screws are not intended for use in exterior environments where they may be exposed to moisture or corrosive elements, as they lack specialized anti-corrosion coatings for outdoor conditions. They are also not suitable for fastening heavy-duty materials or structural components that require high-load bearing capacity beyond standard drywall applications.

Key specifications

• Dimensions: 3.5mm diameter by 45mm length
• Material: High-quality steel
• Quantity: 500 pieces per pack
• Application: Drywall to metal or wood

How to use

To achieve the best results, use a power screwdriver with a depth-limiting attachment to prevent the screw head from tearing through the paper surface of the gypsum board. Position the screw perpendicular to the board surface and drive it in until the head is slightly recessed. Ensure the framing behind the board is stable and properly aligned before beginning the installation process.

What to consider before purchase

• Verify the thickness of your gypsum boards to ensure the 45mm length is appropriate
• Check the material of your framing system to confirm compatibility
• Calculate the total number of screws required based on your wall or ceiling area

Usage recommendations

For optimal results, maintain a consistent spacing between screws, typically every 20 to 30 centimeters along the profile, to ensure even weight distribution and prevent board sagging.
