## Long description

Koelner/Rawlplug TS-4040 4×40 mm is a wood screw with a countersunk (conical) head and a TX (Torx) drive designed for fastening wooden components. The screw’s geometry provides a flush finish when driven into timber, while the TX recess ensures positive engagement with a matching driver, reducing cam-out and enabling reliable torque transfer. This fastener is suited to general woodworking, carpentry, furniture assembly and joinery tasks where a neat, recessed head and secure hold are required.
Advantages
The countersunk head allows the screw to sit flush or below the wood surface for a clean appearance and easier finishing. The TX (Torx) drive offers better contact with the driver compared with standard Phillips or slotted drives, which helps reduce stripping and improves control during installation. The 4×40 mm dimensions provide a balance between holding strength and minimal material displacement, making the screw appropriate for a wide range of softwood and hardwood applications.
Suitable for
Fixing timber framing elements and battens
Furniture assembly and component fastening
Interior joinery and trim installation
General DIY wood projects and repairs
Key specifications
Thread type: wood screw threading for good grip in timber
Head style: countersunk (conical) head for flush installation
Drive type: TX (Torx) drive for improved torque transfer and reduced cam-out
Length: 40 mm
Nominal diameter: 4 mm
Material and finish: suitable for standard interior woodworking (follow manufacturer guidance for specific coatings or corrosion resistance)
How to use
Select a TX driver bit that matches the screw recess and, where appropriate, pre-drill a pilot hole to reduce splitting in hardwood or close-to-edge locations. Position the screw perpendicular to the workpiece and apply steady pressure while driving to ensure the head seats flush into the wood. For countersunk finishes, drive until the head is level with the surface or slightly below, then finish the surface as required with filler or plugs if needed.
Usage recommendations
Use the TS-4040 4×40 mm in interior woodworking applications where a recessed head and reliable driver engagement are important. Pre-drill pilot holes for dense hardwoods and when working close to edges. Match the TX bit size to the screw to avoid cam-out and ensure consistent seating. For exterior or high-moisture environments, select screws with appropriate corrosion-resistant coatings.
