## Long description

Self-tapping wood screw Koelner/Rawlplug TS-3550 3.5x50 mm with a countersunk (conical) head and TX (Torx) drive designed for fastening wooden elements where a flush finish is required. The screw is intended for indoor carpentry, furniture assembly and general woodworking work that needs secure thread engagement in timber. Its conical head allows the fastener to sit level with the surface after installation, reducing the need for additional finishing.
Advantages
The TX (Torx) drive reduces cam-out and enables reliable torque transfer during installation, which helps prevent damage to the screw head. The self-tapping thread cuts into timber for secure holding without pre-drilling in many common softwoods and engineered wood products. The countersunk head provides a neat, flush appearance and simplifies concealment with wood filler or plugs when required.
Suitable for
 Indoor carpentry and wood joinery
 Furniture assembly and fittings
 Fixing trims, skirting boards and mouldings
 General woodworking tasks requiring flush fastening
Key specifications
 Length: 50 mm
 Diameter: 3.5 mm
 Head type: Countersunk (conical) head for flush finish
 Drive type: TX (Torx) for improved torque and reduced cam-out
 Thread type: Self-tapping thread suitable for timber engagement
 Intended use: Indoor wood applications, furniture and trim fastening
How to use
Select a TX driver bit that matches the screw drive and set a drill or driver to an appropriate torque to avoid overdriving. For dense hardwoods or critical joints, pre-drill a pilot hole to the screw core diameter to reduce splitting. Place the screw perpendicular to the workpiece and drive until the head is flush with the surface. If a fully concealed finish is required, countersink slightly deeper and fill or fit a plug over the head.
Usage recommendations
For reliable results, use the screw with compatible timber types and adjust driver torque according to material density. When installing near edges or thin sections, pre-drill to prevent splitting. Store in a dry place to avoid corrosion if not using coated or stainless variants.
