## Long description

Koelner/Rawlplug CS-8240 is a 8x240 mm wood construction screw with a washer-style (pancake) head designed for structural and general timber fastening. The screw combines a long shank and deep thread for reliable pull-out resistance and firm clamping of timber elements. Its wide washer head distributes load over a larger surface to reduce head sinking in soft timber and provides a stable bearing surface for timber-to-timber and timber-to-metal connections.
Advantages
The washer head design ensures broad contact area to minimise damage to the workpiece and improve load distribution. Deep, sharp threads provide good bite into wood for increased holding power and reduced risk of loosening under load. The length and diameter make it suitable for joining thick timbers and multi-layer assemblies without additional connectors. The screw is compatible with power drivers and accepts pilot holes to facilitate accurate alignment and reduce splitting.
Suitable for
Structural timber connections in carpentry and joinery
Fixing beams, posts and joists
Timber-to-timber and timber-to-metal fastening where a broad head is required
Applications requiring deep thread engagement and high withdrawal resistance
Key specifications
Type: wood construction screw with washer-style (pancake) head
Diameter: 8 mm
Length: 240 mm
Head: wide washer/pancake head for increased bearing area
Thread: deep single thread designed for wood engagement
Drive: compatible with power drivers (use appropriate bit)
How to use
Drill an appropriate pilot hole to the recommended diameter and depth for 8 mm screws in the specific timber species to reduce splitting. Position the timber elements accurately and start the screw with a power driver or wrench using the correct bit to maintain alignment. Drive the screw until the washer head sits flush or slightly countersunk against the timber surface, taking care not to over-torque which can damage the timber or deform the head.
Usage recommendations
For best results use pilot holes adapted to the timber hardness and consider applying corrosion protection when used outdoors or in humid environments. Use appropriate safety equipment and follow load-bearing design guidelines when employing these screws in structural connections.
