## Summary description

Koelner construction wood screw CS-8360, size 8×360 mm with a washer-type (podkładkowy) head. Designed for fastening heavy timber elements and structural wood connections, this long 360 mm screw provides deep penetration and strong hold. Suitable for construction, decking, pergolas and general carpentry where durable wood-to-wood or wood-to-structure connections are required.

## Long description

Koelner construction wood screw 8×360 mm washer head CS-8360 is a long fastening screw designed for heavy timber connections and structural wood assemblies. The washer-type head increases bearing surface and distributes load at the contact point, while the substantial 360 mm length ensures deep penetration and a reliable hold in thick timber elements. This screw is suitable for applications where strong, durable wood-to-wood or wood-to-structure joints are required in construction, decking, pergolas and general carpentry.
Advantages
The washer head design provides an expanded load-bearing area that reduces the risk of the head sinking into soft or treated wood. Its long threaded shank achieves secure anchorage through multiple layers of timber, improving joint rigidity and resistance to pull-out. Manufactured for construction use, the screw offers consistent geometry for predictable performance and compatibility with power drivers suitable for long wood fasteners.
Suitable for
Joining heavy timber beams and posts
Fixing decking boards to supporting joists
Assembling pergolas, gazebos and outdoor wooden structures
Structural carpentry and timber framing connections
Repairing or reinforcing wood-to-wood and wood-to-metal connections (with appropriate pre-drilling)
Key specifications
Diameter: 8 mm
Length: 360 mm
Head type: washer-type head to increase bearing area
Intended material: wood and timber structures
Application: long-reach fastening for deep penetration and high pull-out resistance
How to use
Select an appropriate drill or impact driver with a bit that fits the screw head and use a guide or pilot hole to align the screw. For dense or engineered timbers, pre-drill a pilot hole to the screw core diameter to reduce splitting and facilitate insertion. Drive the screw until the washer head bears evenly against the wood surface; avoid over-tightening to prevent crushing the wood or damaging the head. When fastening into assemblies where metal plates or connectors are present, ensure compatibility and consider using washers or sleeves if required.
Usage recommendations
For best results in structural applications, use corrosion-resistant fasteners if the finished structure will be exposed to weather or treated timber. Match pilot hole diameter to timber density and consider using a countersink or driver stop to control depth and protect the wood surface during installation.
