## Summary description

Pack of 14 Koelner/Rawlplug construction screws, size 5.0x40 mm with partial (incomplete) thread and countersunk (conical) head. Designed for joining wooden elements and timber-to-timber connections where a flush head is required. Suitable for structural carpentry, framing and general construction work requiring durable metal fasteners.

## Long description

Pack of 14 Koelner/Rawlplug construction screws sized 5.0 x 40 mm with partial thread and a countersunk (conical) head. These metal fasteners are intended for joining wooden elements where the screw head should sit flush with or below the timber surface. The screws are suitable for structural carpentry, framing and general construction tasks that require reliable screw joints and a neat finish.
Advantages
Partially threaded design allows clamping of two timber pieces together while the smooth shank section draws the pieces tight. Countersunk head provides a flush finish that can be concealed or covered with filler or plugs. Steel construction provides mechanical strength for common woodworking and construction applications. Pack format of 14 pieces is convenient for small projects and on-site repairs.
Suitable for
 Timber-to-timber connections in framing and structural carpentry
 Joining planks, studs and beams where a flush head is required
 General woodworking, decking substructure and small construction repairs
When it may not be suitable
These screws are designed for wood and timber applications. They are not intended for heavy structural elements that require certified structural connectors or for direct use in masonry, concrete, or metal without appropriate anchors or inserts. If corrosion resistance for exterior or coastal use is required, check the screw material and coating before use.
Key specifications
 Diameter: 5.0 mm
 Length: 40 mm
 Thread type: partial (incomplete) thread with smooth shank section
 Head type: countersunk (conical) head for flush seating
 Material: steel (metal fastener)
 Quantity in pack: 14 pieces
How to use
Pre-drill a pilot hole appropriate to the timber species and screw diameter to reduce splitting. Position the two timber elements, insert the screw and drive it using a compatible screwdriver or bit, keeping the screw aligned to avoid angling. Drive until the head is flush with the timber surface; countersunk heads can be sunk slightly below the surface if the application requires concealment. For load-bearing or safety-critical joints, follow applicable building regulations and use appropriate spacing and fastening patterns.
What to consider before purchase
 Confirm the screw diameter and length suit the timber thickness and joint design
 Verify material and coating for suitability in interior or exterior environments
 Consider using appropriate pilot hole diameters to prevent wood splitting
 For structural or safety-critical applications, ensure compliance with local building codes
Usage recommendations
Use a correct-size pilot bit and a compatible driver bit to improve driving performance and reduce head damage. For exterior use, select screws with suitable corrosion protection. Space and pattern fasteners according to load and design requirements to ensure secure, durable joints.
