## Summary description

Koelner/Rawlplug CS-8100 is an 8x100 mm wood construction screw with a washer-style (podkładkowy) head designed for secure timber connections.

Provides strong holding power and easy installation with appropriate pilot drilling and compatible drivers.

## Long description

Koelner/Rawlplug CS-8100 8x100 mm is a wood construction screw with a washer-style head designed for timber connections. The screw is intended to join wooden elements and to fasten wood to composite substrates, delivering reliable mechanical fastening when used with appropriate pre-drilling and compatible drivers. Its dimensions and head form make it suitable for structural and non-structural woodworking tasks where a broad bearing surface is required.
Advantages
The washer-style head increases the bearing area on the timber surface, reducing the risk of head pull-through and improving load distribution. The screw's length and thread profile provide strong holding power in solid wood and engineered wood products. Designed for straightforward installation, the fastener is compatible with common electric drivers and standard pilot drilling practice, resulting in consistent, repeatable connections.
Suitable for
 Joining timber members in frame and subframe assemblies
 Securing decking boards, joists and rafters
 Fixing wooden cladding or trims to timber supports
 Attaching wood to composite or laminated wood panels
Key specifications
 Material: corrosion-resistant steel (typical for wood construction screws)
 Head type: washer-style (increases bearing surface)
 Diameter: 8 mm
 Length: 100 mm
 Thread: full/partial thread suitable for wood fastening (ensures grip in timber)
How to use
Select an appropriate pilot drill bit for the 8 mm diameter screw based on timber species and density, and drill pilot holes to the required depth to avoid splitting. Place the screw so the washer-style head sits flush against the timber surface and drive using an electric driver with the correct bit. Apply steady pressure and moderate speed to seat the screw without over-tightening. For connections that transfer structural loads, follow relevant building codes and fastening spacing guidelines.
Usage recommendations
For best results, pre-drill pilot holes and use a driver with torque control to prevent overdriving. In exterior or high-humidity applications, ensure compatibility between the screw coating and the timber or consider additional corrosion protection as required by the installation conditions.
