## Summary description

Koelner/Rawlplug CS-8160 is a wood construction screw sized 8x160 mm with a washer-style head. Designed for timber connections and structural fixing, it provides secure fastening in wood and composite materials. Suitable for framing, decking and general carpentry where long 160 mm screws are needed for deep penetration and strong joints.

## Long description

Koelner/Rawlplug CS-8160 8x160 mm washer head screw is a wood construction screw engineered for timber connections and structural fastening. With an 8 mm diameter and 160 mm length, it offers deep penetration for reliable joints in solid wood and composite timber materials. The washer-style head increases bearing surface and helps distribute load to reduce surface indentation and improve clamping in frame, decking and heavy carpentry applications.
Advantages
The design combines a long threaded shank for strong withdrawal resistance and a washer head for even load distribution at the work surface. Hardened steel construction and a corrosion-resistant coating ensure durability in indoor and covered outdoor installations. Precision threading and a self-drilling lead tip simplify installation, reduce splitting in timber, and allow secure connections without pre-drilling in many applications.
Suitable for
Framing and structural timber connections
Decking joists and ledger attachments
Heavy carpentry and joinery where deep‑penetration screws are required
Securing laminated beams and composite wood elements
Key specifications
Diameter: 8 mm
Length: 160 mm
Head type: washer head for improved bearing
Material: hardened steel with corrosion-resistant coating
Thread: full or long-thread design for strong withdrawal resistance
Tip: self-drilling/self-tapping lead to ease installation in timber
How to use
Select a screw length that provides sufficient embedment in the receiving timber while avoiding penetration into concealed spaces. Position the washer head flush to the timber surface and drive the screw with an appropriate handheld or powered driver using the correct bit. Apply steady pressure and moderate speed to seat the screw without over-torquing. For best results in certain hardwoods or near board ends, consider pilot drilling to minimize splitting.
Usage recommendations
Use these screws for indoor and covered outdoor timber work; verify compatibility with treated wood and follow coating manufacturer guidance for external exposure. Store in a dry place to preserve the corrosion-resistant finish and choose appropriate screw spacing and edge distances according to structural requirements.
