Wood screw Koelner/Rawlplug TS-3545 3.5x45 mm, countersunk head, TX drive

Koelner/Rawlplug TS-3545 is a 3.5x45 mm wood screw featuring a countersunk head and a TX (Torx) drive. It is built for fastening wooden elements where a flush finish is required; the countersunk head allows the screw to sit level with or below the timber surface. The Torx drive reduces cam‑out and enables higher torque transfer with compatible drivers, improving assembly consistency in joinery and light carpentry tasks.

Advantages

The TS-3545 screw offers precise thread engagement in timber for reliable pull‑out resistance and dimensional stability. Its countersunk head provides a neat, recessed finish suitable for visible surfaces or for subsequent filling and sanding. The TX drive design ensures secure bit fit, reducing driver slippage and wear on both screw and tool. Made for common indoor woodworking and furniture applications, the screw balances holding power with ease of installation.

Suitable for

• Indoor woodworking and carpentry
• Furniture assembly and repair
• Joining timber components and frames
• Fixing trims, mouldings and fixtures where a countersunk finish is desired

Key specifications

• Diameter: 3.5 mm
• Length: 45 mm
• Head type: Countersunk (flat) head for flush seating
• Drive type: TX (Torx) drive for improved torque transfer
• Material: Steel (suitable for indoor use; surface finish varies by batch)
• Thread: Wood screw thread profile optimized for timber engagement

How to use

Select a compatible TX driver bit and, if desired, pre‑drill a pilot hole appropriate for the timber species and screw diameter to reduce splitting. Position the screw and drive it steadily until the countersunk head reaches the desired flush or slightly recessed position. For hardwoods, use a slightly larger pilot hole; for softwoods, a smaller pilot hole or self‑tapping insertion is typically acceptable. Ensure consistent torque to avoid over‑driving and damaging the timber or the screw head.

Usage recommendations

Use the TS-3545 in interior, dry environments and avoid prolonged exposure to moisture unless the screw has a corrosion‑resistant coating. Match driver size to the TX drive to minimize cam‑out, and consider finishing steps such as countersink adjustment, filling and sanding when a smooth surface is required.
