Wood construction screw Koelner/Rawlplug TS-5080 5x80 mm, countersunk head, TX drive

Koelner/Rawlplug TS-5080 is a wood construction screw 5x80 mm with a countersunk (conical) head and TX (Torx) drive intended for fastening wooden elements in construction and carpentry. The screw geometry provides reliable clamping of joints, frames and structural assemblies in common wood substrates. It is suitable for use with pre-drilled or pilot holes and standard woodworking tools equipped with a Torx bit.

Advantages

The countersunk head enables a flush finish with the workpiece surface, reducing the need for additional trimming. The TX drive reduces cam-out and allows higher torque transmission compared with slotted or Phillips drives, improving installation speed and consistency. The screw length and thread profile are chosen to deliver secure pull-out resistance and stable joint compression for typical construction-grade timber.

Suitable for

• Fastening structural timber elements such as joists, studs and beams
• Carpentry and joinery assemblies including frames and furniture substructures
• Outdoor wooden constructions when used with appropriate corrosion-resistant material or coatings
• Applications requiring a flush surface finish, for subsequent finishing or painting

Key specifications

• Nominal diameter: 5 mm
• Length: 80 mm
• Head type: countersunk (conical) for flush installation
• Drive type: TX (Torx) for improved torque transfer
• Thread: full or partial thread suitable for wood-to-wood connections

How to use

Select an appropriate Torx bit and, when required, drill a pilot hole sized to the timber and screw diameter to avoid splitting. Position the screw perpendicular to the workpiece and drive it with a cordless or corded screwdriver at moderate speed, applying steady pressure until the head sits flush with the surface. For repetitive work, use a torque-limited driver to avoid over-driving and damaging the wood or screw head.

Usage recommendations

Use corrosion-resistant screws or protective coatings for prolonged outdoor exposure. Pre-drill clearance holes in hardwoods or near edges to prevent splitting. Match screw length to the combined thickness of joined members to ensure adequate penetration without protrusion.
