Koelner FS-3555 Drywall and Profile Screws 3.5x55mm, 500 pieces

The Koelner FS-3555 drywall and profile screws are professional-grade fasteners engineered for the efficient installation of gypsum boards onto metal or wooden framing. Measuring 3.5x55mm, these screws are designed to provide a secure and durable connection in various interior construction applications. Each screw features a sharp, hardened point that allows for rapid penetration into materials, reducing the time required for installation while ensuring a stable grip.

Advantages

These screws offer exceptional performance due to their specialized design, which includes a countersunk head that sits flush with the surface of the drywall, creating a smooth finish that is easy to fill and paint. The high-quality steel construction ensures resistance to snapping during the driving process, while the sharp point minimizes the risk of damaging the board surface. With a pack size of 500 pieces, these fasteners provide a cost-effective and reliable solution for both small-scale renovations and large-scale professional construction projects.

Suitable for

• Mounting gypsum boards to metal profiles
• Attaching drywall to wooden studs
• Interior finishing and wall cladding
• Renovation and partition wall construction

When it may not be suitable

These screws are not intended for use in exterior environments where exposure to moisture or corrosive elements could lead to rust. They are also not suitable for fastening heavy-duty materials or structural steel components that require specialized heavy-duty anchors.

Key specifications

• Dimensions: 3.5mm diameter by 55mm length
• Head type: Countersunk
• Point type: Sharp
• Material: Hardened steel
• Quantity: 500 pieces

How to use

To use these screws, ensure you are using a compatible screwdriver or a power drill with a depth-limiting attachment to prevent over-driving the screw into the gypsum board. Position the drywall panel against the profile and drive the screw through the board until the head is slightly below the surface level, creating a small dimple for joint compound. Maintain a consistent spacing between screws according to the manufacturer's guidelines for the specific board thickness being installed.

What to consider before purchase

• Check the thickness of your drywall to ensure the 55mm length is appropriate for your application
• Verify the material of your profiles to ensure compatibility with the sharp point design
• Calculate the total number of screws needed based on the surface area of your project

Usage recommendations

Always wear appropriate personal protective equipment, such as safety glasses, when installing screws to protect against debris. Ensure the power tool clutch is correctly adjusted to avoid damaging the paper surface of the gypsum board.
