Wood construction screw Koelner/Rawlplug TS-6160 6x160 mm, countersunk head, TX drive

Koelner/Rawlplug wood construction screw TS-6160 6x160 mm is a fastener designed for joining timber elements where a flush, countersunk finish is required. The 6 mm diameter and 160 mm length provide sufficient penetration for solid connections in structural and non-structural carpentry, decking, and other timber assemblies. The conical head sits flush with the wood surface after installation and the TX drive allows efficient torque transfer and reduced cam-out during driving.

Advantages

The countersunk head ensures a neat, level surface that can be covered or left visible depending on the application. The TX (Torx) drive provides secure bit engagement for higher torque and reduced stripping compared with slotted or Phillips drives. The length and diameter combination gives good holding power in solid timber and engineered wood, enabling reliable connections for load-bearing and non-load-bearing joints. The screw geometry is suitable for direct fastening without the need for additional metal connectors in many standard woodworking tasks.

Suitable for

• Structural and non-structural timber framing
• Deck construction and pergola assembly
• Carpentry and joinery applications requiring a flush finish
• Fixing thick timber elements, beams and posts

Key specifications

• Diameter: 6 mm
• Length: 160 mm
• Head type: Countersunk (conical) head for flush installation
• Drive type: TX (Torx) drive for improved torque transfer
• Intended material: Solid timber and engineered wood products

How to use

Pre-drilling is recommended for hardwoods or where precise alignment is required; select a pilot hole slightly smaller than the screw shank to ensure proper thread engagement. Use a compatible TX bit and an adjustable torque setting on the driver to avoid over-tightening and potential splitting. Drive the screw until the countersunk head is flush with or slightly below the wood surface, depending on whether a plug or filler will be applied. For repetitive work, a screw gun with depth control improves consistency and installation speed.

Usage recommendations

For best results, match screw length to the combined thickness of the elements being joined so that adequate thread engagement is achieved in the receiving member. When working near edges, space fasteners to minimise the risk of splitting and consider pre-drilling. For exterior or high-moisture environments, select appropriate corrosion-resistant fastening options or coatings compatible with the timber used.
