Wood screw Koelner/Rawlplug TS-3030 3x30 mm, countersunk head, TX drive

Koelner/Rawlplug TS-3030 3x30 mm is a wood screw with a countersunk (conical) head and a TX (Torx) drive designed for secure timber-to-timber connections and fixture mounting. The 3 mm shank diameter and 30 mm length suit a wide range of joinery tasks where a flush finish is required; the countersunk head sits level with the wood surface after installation. The TX drive reduces cam-out and allows higher torque transfer compared with slotted or Phillips drives, improving efficiency when using power drivers or manual Torx bits.

Advantages

The screw’s countersunk head provides a flush appearance and prevents protrusions that could interfere with further processing or finishing. The TX drive profile ensures stable engagement between bit and fastener, reducing stripping and enabling faster, more reliable installation. Threading is optimised for wood applications to deliver strong grip in softwoods and hardwoods when pre-drilling guidelines are followed. The 3x30 mm size offers a balance between holding power and minimal material displacement, making it suitable for light to medium wood assemblies.

Suitable for

• Furniture assembly and fittings
• Interior carpentry and joinery
• Mounting fixtures and brackets to wooden surfaces
• Wooden frame and panel connections
• DIY repairs and small construction projects

Key specifications

• Diameter: 3 mm
• Length: 30 mm
• Head type: Countersunk (conical)
• Drive type: TX (Torx)
• Material: Steel (typical for wood screws)
• Finish: Standard zinc or passivated coating (for corrosion resistance in interior use)
• Thread type: Wood-thread designed for timber engagement

How to use

Select a TX bit matching the screw drive size and, where appropriate, pre-drill a pilot hole to the screw core diameter to prevent wood splitting—especially in hardwoods or near edges. Position the screw perpendicular to the workpiece and apply steady torque using a manual TX driver or a power driver set to a controlled torque setting. Drive the screw until the countersunk head is flush with the surface; avoid over-tightening to prevent burying the head too deep or damaging the surrounding wood. For exterior or high-moisture applications, use screws with an appropriate corrosion-resistant finish.

Usage recommendations

For best results, match pilot hole diameter to wood species and screw core diameter, and use a torque-limited driver when working with thin panels or softwood to maintain a secure connection without damaging the material.
