## Summary description

## Long description

Pack of 42 Koelner/Rawlplug construction screws R-S3-PTX-30025 with partial thread and countersunk (conical) head, size 3.0×25 mm. These screws are intended for joining wood, chipboard and similar building materials where a flush finish is required. The partial thread and conical head design allow the screw to pull parts together while the countersunk head sits flush with the surface after installation.
Advantages
The partial thread provides strong clamping of joined parts by allowing the unthreaded shank to act as a dowel, reducing shear stress in the material. The countersunk conical head ensures a neat, recessed finish suitable for carpentry and interior installation, eliminating protruding heads. Supplied in a pack of 42, these screws are convenient for medium-sized projects and repairs where consistent size and head type are required.
Suitable for
 Joining wooden components and furniture assembly
 Fixing chipboard, MDF and similar panel materials
 Interior installation work where a flush finish is needed
 Carpentry tasks and structural fastening of lightweight elements
When it may not be suitable
These screws are not intended for high-load structural connections in heavy construction or for use in metal-to-metal fastening. They may not be suitable for exterior applications unless a corrosion-resistant coating or stainless variant is specified, since prolonged exposure to moisture can affect standard steel fasteners.
Key specifications
 Quantity: 42 pieces per pack
 Thread type: partial thread
 Head style: countersunk (conical) head
 Nominal diameter: 3.0 mm
 Length: 25 mm
 Intended materials: wood, chipboard, MDF and similar construction panels
How to use
For reliable results, pre-drill a pilot hole appropriate to the screw diameter and the density of the material to avoid splitting thin or brittle panels. Insert the screw with a compatible Phillips or Pozidriv driver bit, applying steady pressure until the head sits flush with the surface. For best holding, ensure the mating surfaces are aligned before tightening so the partial thread can draw the pieces together. In hard woods or dense panels, reduce driving speed and use a pilot drill to preserve the screw and workpiece.
What to consider before purchase
 Whether a partial-thread screw is appropriate for the joint type you need
 Material compatibility (wood, chipboard, MDF) and whether corrosion resistance is required
 Required screw length and diameter for the thickness of joined parts
 Head type preference — countersunk head for flush finish
Usage recommendations
Use a correctly sized pilot hole and the appropriate driver bit to achieve a secure, flush installation. For visible surfaces, countersink slightly deeper if you plan to apply plugs or filler for a seamless finish. Store the pack in a dry place to preserve the coating and prevent corrosion.
