Construction wood screw Koelner 6×60 mm, countersunk head, TX drive (model TS-6060)

Koelner construction wood screw 6×60 mm with a countersunk head and TX (Torx) drive is engineered for secure timber connections in structural and general carpentry applications. The screw’s geometry provides firm thread engagement in softwood and hardwood, enabling stable load-bearing joints and precise assembly of frames, decking, and wooden furniture components. The countersunk head sits flush with the surface after installation for a neat finish and reduced snagging.

Advantages

This fastener combines a countersunk head profile with a Torx drive to reduce cam-out and allow higher torque transfer during installation. The 6 mm diameter and 60 mm length balance shear strength and penetration depth for common timber tasks. Its thread design ensures reliable pull-out resistance and consistent seating, supporting structural joins and repetitive assembly work with predictable results.

Suitable for

• Joining structural timber elements and beams
• Assembling wooden frames and studwork
• Building decks, terraces, and outdoor wooden platforms
• Furniture assembly and fastening panels to frames
• General carpentry, renovation, and repair tasks

Key specifications

• Diameter: 6 mm
• Length: 60 mm
• Head type: countersunk (flush finish)
• Drive type: TX (Torx) for improved torque transmission
• Material and coating: suitable for timber applications (see packaging for specific finish)
• Thread: full/part thread optimized for wood engagement

How to use

Select an appropriate pilot hole size if working with hardwoods or where splitting is a concern; softwoods may accept direct insertion. Use a Torx bit matching the TX drive to avoid cam-out and strip damage. Drive the screw until the countersunk head is flush with or slightly below the timber surface, taking care not to over-torque which can weaken the joint or damage the head. For structural connections, follow relevant building standards and joinery practices regarding spacing, edge distance, and number of fasteners.

Usage recommendations

For optimal performance, pre-drill holes when installing near edges or in dense hardwoods, and use appropriate corrosion-resistant coatings or fastener grades for outdoor or treated timber. Apply consistent torque and use washers only when specified by design requirements.
