Wood construction screw Koelner/Rawlplug TS-6200 6x200 mm, countersunk head, TX drive

Wood construction screw Koelner/Rawlplug TS-6200 6x200 mm is a long wood screw engineered for joining and fixing wooden elements in construction and carpentry. The screw features a countersunk (conical) head that sits flush with the surface after installation and a TX (Torx) drive for reliable torque transfer and reduced cam‑out. With a 200 mm length and a 6 mm diameter, it provides deep penetration and extended engagement in timber members when used with appropriate pre‑drilling.

Advantages

The countersunk head enables a neat, flush finish suitable for surface treatments or concealed connections. The TX drive improves bit retention and allows higher installation torque compared with conventional Phillips or slotted drives. The long threaded length ensures secure clamping and load distribution across joined wooden elements. Designed for construction use, the screw is suitable where deep anchoring and strong withdrawal resistance are required.

Suitable for

• Timber-to-timber structural and non-structural connections
• Decking, joist and beam fastening where long penetration is needed
• Carpentry, roof battens, and heavy timber assemblies
• Applications requiring a flush countersunk finish for surface treatments

Key specifications

• Length: 200 mm
• Diameter: 6 mm
• Head type: Countersunk (conical) head
• Drive type: TX (Torx) drive
• Thread: Full/long threaded length for deep engagement in wood
• Material and coating: Suitable for typical construction timber use (follow manufacturer guidance for exposure and corrosion resistance)

How to use

Select a compatible TX bit and, where indicated, pre‑drill a pilot hole sized appropriately for the timber species and screw diameter to avoid splitting. Position the screw and drive it with a drill/driver set to an appropriate torque setting; use steady pressure and maintain alignment to the workpiece so the countersunk head seats flush. For load‑bearing connections, follow applicable building codes and fastening patterns and verify embedment depth and clamping between members.

Usage recommendations

Use corrosion‑resistant fasteners or appropriate protective coatings when installing in exterior, humid, or chemically treated timber. Match pilot hole diameter to the wood density and always use the correct TX bit size to minimize tool wear and ensure full engagement of the drive.
