## Summary description

Construction wood screw Koelner/Rawlplug, size 8x180 mm, washer (flanged) head, model CS-8180 (EAN 5906675454696). Designed for secure fastening of wooden structural elements and heavy-duty timber connections. Suitable for straight insertion into wood, glulam, and laminated beams where long, high-strength fasteners are required for framing, decking, pergolas and structural repairs.

## Long description

Wood construction screw Koelner/Rawlplug 8x180 mm washer head CS-8180 is a high-strength fastener engineered for structural wooden connections. The 8 mm diameter and 180 mm length provide deep embedding and strong withdrawal resistance, while the flanged washer head ensures an even load distribution at the contact surface. This screw is intended for direct insertion into solid wood, glued laminated timber (glulam) and laminated beams where long, reliable fasteners are required for framing, decking, pergolas and structural repairs.
Advantages
The screw combines a robust shank dimension with a large washer head to reduce the need for additional washers and to minimize surface indentation. Its length and diameter give high shear and pull-out capacity for heavy-duty timber connections. The design supports straight insertion into wood members without pre-drilling in many applications, streamlining installation time. Materials and coating provide corrosion resistance appropriate for typical above-ground timber construction.
Suitable for
 Framing and load-bearing wooden structures
 Deck installation and repair
 Pergolas, gazebos and outdoor wooden constructions (above-ground)
 Joining glulam and laminated beams
 Structural timber repairs and retrofit connections
Key specifications
 Diameter: 8 mm
 Length: 180 mm
 Head type: washer (flanged) head for increased bearing area
 Intended use: wood-to-wood structural fastening
 Suitable materials: solid timber, glulam, laminated beams
 Mechanical properties: designed for high shear and pull-out resistance in timber
How to use
Position the screw through the prepared timber elements ensuring correct alignment for the intended load path. For dense hardwoods or where exact positioning is critical, pre-drilling a pilot hole sized to the screw core diameter is recommended to avoid splitting. Drive the screw until the washer head sits flush against the timber surface, taking care not to over-tighten which may compress the wood or deform the head. Use an appropriate power driver or impact tool with the matching bit for faster and controlled installation.
Usage recommendations
For exterior or high-humidity environments, combine these screws with appropriate timber treatments and consider corrosion-class fasteners or additional protective coatings. When used in structural applications, follow local building codes and engineering specifications regarding spacing, edge distances and load calculations.
