Wood screw Koelner/Rawlplug TS-4035 4x35 mm, countersunk head, TX drive

Koelner/Rawlplug TS-4035 4x35 mm is a wood screw designed for fastening wooden elements where a flush finish is required. The screw has a 4 mm shank diameter and 35 mm length with a countersunk (conical) head that sits level with the surface after installation. A TX (Torx) drive reduces cam-out and allows efficient torque transfer when used with compatible bits and power drivers. The product is suitable for joinery, interior fixtures and general woodworking where a reliable mechanical connection is needed.

Advantages

The countersunk head provides a neat, recessed finish that can be concealed or left flush without protrusion. The TX (Torx) drive improves engagement between bit and screw, reducing slipping and wear on the fastener and tool. The screw’s dimensions (4x35 mm) make it versatile for a variety of medium-thickness wooden assemblies, offering secure holding and straightforward application with both manual and powered drivers.

Suitable for

• Assembling wooden furniture and cabinets
• Fixing interior trim and moldings
• General carpentry and joinery tasks
• Attaching fixtures to wooden substrates

Key specifications

• Shank diameter: 4 mm
• Length: 35 mm
• Head type: countersunk (conical) head for flush installation
• Drive type: TX (Torx) drive for improved torque transfer
• Suitable for: wooden materials and composite wood products

How to use

Select a Torx bit that matches the TX drive size of the screw and fit it in a compatible manual or powered driver. If working with hardwood or near edges, pre-drill a pilot hole of appropriate diameter and depth to prevent splitting and ensure accurate seating. Place the screw so the countersunk head aligns with the surface and drive it in until the head is flush or slightly below the surface if concealment is desired. Clean any debris from the hole and test the connection for stability.

Usage recommendations

For best results, use a variable-speed driver set to a controlled torque to avoid overdriving. When fixing thin panels or working close to edges, use a pilot hole and consider a screw length that provides adequate thread engagement without piercing through the opposite face.
