## Summary description

Construction screw for wood Koelner/Rawlplug CS-8280, size 8x280 mm with a washer (bearing) head. Designed for fastening timber elements, beams and structural connections where long-thread reach is required. Suitable for load-bearing and non-load-bearing wooden assemblies; provides strong withdrawal resistance and easy installation with appropriate driver bit.

## Long description

Wood construction screw Koelner/Rawlplug CS-8280 8x280 mm washer head is a heavy-duty fastener designed for joining timber elements and structural wooden connections. The long 280 mm length and 8 mm diameter provide deep embedment and high withdrawal resistance in solid timber, glulam, and laminated timber. The integrated washer head ensures secure bearing against the material surface, reducing the risk of pull-through and improving load distribution. The screw is intended for use with an appropriate driver bit and compatible power tool for efficient installation.
Advantages
The CS-8280 screw offers strong withdrawal resistance thanks to its long threaded shank and 8 mm diameter, making it suitable for load-bearing and non-load-bearing wooden assemblies. The washer head design increases contact area and distributes clamping force to prevent surface damage and improve joint stability. Installation is straightforward with the correct driver bit, allowing faster work compared with lag bolts that require pre-drilling for the head seating. The product is suitable for use in structural timber applications where deep penetration and reliable fastening are required.
Suitable for
 Fixing beams and joists in timber frames
 Connecting wooden posts and structural elements
 Securing heavy timber cladding and facades
 Fastening rafters and roof structures
 Repair and reinforcement of wooden structures
Key specifications
 Diameter: 8 mm
 Length: 280 mm
 Head type: washer (bearing) head for increased contact area
 Thread: full-length thread suitable for deep timber penetration
 Material and finish: metal construction designed for structural fastening (refer to manufacturer for specific coating)
 Drive: compatible with appropriate driver bit for power tool installation
How to use
Select an appropriate driver bit and a power tool capable of handling long structural screws. Where required by project specifications or timber type, pre-drill a pilot hole equal to the core diameter to reduce splitting in hardwoods; softwoods may accept direct driving depending on size. Position the washer head flush against the timber surface and drive the screw until the head bears securely without crushing the surrounding wood. For structural connections follow relevant building codes and fastening patterns to ensure load distribution and stability.
Usage recommendations
Use corrosion-resistant screws or appropriate coatings in outdoor, damp, or chemically treated timber applications. Verify load requirements and local building regulations for structural installations; when in doubt, consult a structural engineer or the manufacturer’s technical guidance. Store screws in a dry place and handle long screws with care during installation to avoid bending.
