Wood screw Koelner/Rawlplug TS-5025 5x25 mm, countersunk head, TX drive

Koelner/Rawlplug TS-5025 wood screw, size 5x25 mm, is a fastener designed for joining wooden elements, light carpentry and general joinery. The screw features a countersunk (conical) head that allows a flush finish and a Torx (TX) drive for secure torque transfer and reduced cam-out. Its dimensions make it suitable for medium-thickness boards and fixtures where a concealed head and reliable clamping are required.

Advantages

The countersunk head provides a neat, flush surface when driven into wood, preventing protrusion and facilitating subsequent finishing. The TX drive improves bit engagement and torque control compared with slotted or Phillips heads, reducing the risk of stripping during installation. The screw's thread and length balance holding power and penetration depth for typical woodworking and joinery tasks.

Suitable for

• Fixing wooden boards and panels
• Joinery and furniture assembly
• Light carpentry and interior woodwork
• Situations requiring a flush, concealed head

Key specifications

• Diameter: 5 mm
• Length: 25 mm
• Head type: countersunk (conical)
• Drive type: Torx (TX)
• Material: steel (zinc-plated or similar finish commonly applied to wood screws)
• Application: for fastening in wood and wood-based materials

How to use

Select an appropriate Torx bit for the TX drive to ensure correct engagement. For dense or hardwoods, pre-drill a pilot hole of suitable diameter to reduce splitting; for softwoods a smaller pilot hole or self-tapping insertion may be sufficient. Place the countersunk head flush with the wooden surface or slightly below if you plan to fill or cover the head. Drive the screw with a hand driver or a low-speed power driver, applying steady pressure and avoiding over-tightening to prevent head damage or thread stripping.

Usage recommendations

Use compatible Torx bits and match pilot hole size to the wood species to achieve optimal holding and avoid splitting. For exterior or high-moisture applications select coated or stainless variants appropriate to environmental conditions.
