Screw for wood Koelner/Rawlplug TS-3025 3×25 mm countersunk head, TX drive

Wood screw Koelner/Rawlplug TS-3025 3×25 mm features a countersunk (conical) head and a TX (Torx) drive. It is designed to secure wooden components with a flush finish, providing reliable threaded engagement in a variety of timber types. Intended for woodworking tasks such as carpentry and furniture assembly, this screw offers controlled insertion and reduced cam‑out when used with the appropriate TX driver.

Advantages

The countersunk head enables the screw to sit flush with or below the wood surface for a neat appearance and easier post‑processing. The TX drive improves torque transfer and minimizes driver slippage, allowing faster and more consistent installation compared with slotted or Phillips drives. The thread profile is optimized for wood, providing secure holding power in softwoods and hardwoods when matched with suitable pilot holes.

Suitable for

• General carpentry and joinery work
• Furniture assembly and repairs
• Fixing trim, moldings and panels
• Interior wooden constructions and fittings

Key specifications

• Threaded length and diameter: 3 mm diameter, 25 mm overall length
• Head type: countersunk (conical) head for flush mounting
• Drive type: TX (Torx) drive for improved torque transmission
• Material and finish: steel fastener suitable for wood applications (verify suitability for exposure conditions)
• Intended use: fastening into timber with appropriate pilot drilling depending on wood density

How to use

Select an appropriate TX driver matching the drive size and set the screwdriver or drill to a controlled torque setting to avoid over‑driving. For dense hardwoods, drill a pilot hole to the recommended diameter and depth to prevent splitting; for softwoods a smaller pilot hole or direct insertion may be acceptable. Place the screw head flush with the wood surface or countersink slightly below the surface if a concealed finish is required. Tighten until the head is seated and the joint is secure, taking care not to over‑compress the material.

Usage recommendations

Use pilot holes that match the screw diameter and wood type; apply appropriate torque and use a TX bit to reduce cam‑out. For external or high‑moisture applications choose fasteners with corrosion‑resistant coatings or alternate materials suitable for exposure.
