Wood screw Koelner/Rawlplug TS-3535 3.5x35 mm, countersunk head, TX drive

Koelner/Rawlplug TS-3535 is a wood screw with dimensions 3.5 x 35 mm, featuring a countersunk (conical) head and a TX (Torx) drive. It is intended for fastening wooden components where a flush finish is required and reliable torque transfer is important. The screw's geometry and thread profile are designed to provide firm engagement in timber and common wood-based materials used in furniture making, carpentry and general joinery.

Advantages

The countersunk head allows the screw to sit flush with or below the wood surface, enabling neat finishing and easy covering with plugs or filler. The TX drive reduces cam-out and enables efficient torque transfer, supporting consistent tightening and lower risk of driver slippage. Its size and thread design provide secure mechanical connection in solid wood and typical engineered wood panels, offering predictable holding power for assembly tasks.

Suitable for

• Furniture assembly and repair
• Carpentry and joinery work
• Fixing wooden trim, battens and connectors
• Light structural wood connections where a recessed head is required

Key specifications

• Diameter: 3.5 mm
• Length: 35 mm
• Head type: Countersunk (conical)
• Drive type: TX (Torx)
• Material: Suitable for timber and wood-based panels (see product packaging for material finish)

How to use

Select an appropriate TX driver or bit that matches the screw head. Where necessary, pre-drill a pilot hole according to the wood type and screw diameter to minimise splitting, especially near edges or in hard timbers. Insert the screw and drive it until the head is flush with or slightly below the wood surface depending on your finishing needs. Avoid excessive torque once the head is seated to prevent over-tightening or head stripping.

Usage recommendations

For best results, match pilot hole diameter and depth to the material density; use corrosion-resistant or coated screws for exterior or high-humidity applications; when a completely concealed finish is required, countersink slightly deeper and use appropriate plugs or fillers.
