## Summary description

Construction wood screw Koelner 4x16 mm with a countersunk (conical) head and TX (Torx) drive, MPN TS-4016, EAN 5906675455136. Intended for joining wooden elements in carpentry and general construction. Common use includes furniture assembly, framing, and fittings where a flush finish is required. Provides reliable fastening for timber applications.

## Long description

Koelner construction wood screw 4x16 mm with a countersunk head and TX (Torx) drive is designed for fastening wooden elements where a flush surface finish is required. The screw's size and head shape make it suitable for joining thin timber parts, trim, fittings and light framing components. The TX drive provides positive engagement with the driver and reduces cam-out compared with slotted or Phillips drives.
Advantages
The countersunk (conical) head allows the screw to sit flush or slightly below the wood surface after installation, enabling neat finishing and easy covering with filler or plugs. The Torx (TX) drive ensures reliable torque transfer and reduces stripping of the screw head during repeated use. The 4x16 mm dimensions deliver a balance of holding power and minimal splitting risk in common soft and hardwoods when used with appropriate pilot holes or pre-drilling techniques.
Suitable for
 Furniture assembly and repair
 Interior trim and molding installation
 Light framing and substructures
 Cabinetry and fittings
 General carpentry tasks requiring a flush finish
Key specifications
 Threaded fastener type: wood screw with full or partial threading suitable for timber joining
 Dimensions: 4 mm nominal diameter × 16 mm length
 Head style: countersunk (conical) head for flush installation
 Drive type: TX (Torx) for improved torque transfer and reduced cam-out
 Typical materials: intended for use in softwoods and hardwoods, engineered wood products and composite boards
How to use
Select an appropriate Torx driver or bit that matches the TX drive size of the screw. For hardwoods or when close to edges, drill a pilot hole of suitable diameter and depth to reduce splitting and ensure accurate alignment. Position the screw head flush with the wood surface by driving it until the countersunk head is seated; avoid over-tightening to prevent compression damage to the timber or stripping of the head. Remove any debris from the hole prior to insertion for consistent seating.
Usage recommendations
Use these screws with correct pilot holes and compatible Torx drivers for best results; apply corrosion-resistant screws or surface treatments if used in humid environments or exterior applications not protected from moisture.
