## Long description

Koelner TS-5120 5×120 mm is a construction wood screw with a countersunk (conical) head and TX (Torx) drive. Designed for fastening wooden elements in construction and carpentry, this screw provides a recessed finish and efficient torque transfer through the TX profile. It is intended for wood-to-wood connections where a flush head and secure clamping are required.
Advantages
The countersunk head allows the screw to sit flush with or below the wood surface, creating a neat finish and reducing protrusions. The TX drive improves bit engagement and reduces cam-out, enabling higher torque application and easier driving with power tools. The thread profile is optimized for wood to provide good pull-out resistance and consistent penetration.
Suitable for
 Structural timber joints and framing
 Decking subframes and outdoor wood substructures
 Carpentry assemblies and general wood-to-wood connections
Key specifications
 Nominal diameter: 5 mm
 Length: 120 mm
 Head type: conical (countersunk) head for flush installation
 Drive type: TX (Torx) for improved torque transfer and reduced slippage
 Material: steel (suitable for load-bearing wood fixings)
 Thread: wood-thread profile for secure gripping in timber
How to use
Select an appropriate TX driver bit that matches the drive size. When fastening, position the screw perpendicular to the wood surface and apply steady pressure while driving with a manual or powered driver. For hardwoods or where precise alignment is needed, pre-drilling a pilot hole can reduce splitting and ensure correct seating. Drive the screw until the head is flush with or slightly below the wood surface as required for your application.
Usage recommendations
Use appropriate corrosion protection or coated fasteners when installing in exterior or high-humidity environments; ensure bit and driver are in good condition to prevent damage to the TX recess. For load-bearing connections follow applicable building codes and fastening spacing guidelines.
