## Summary description

Pack of 48 Koelner/Rawlplug construction screws R-S3-PTX-30020, size 3.0 x 20 mm with partial (incomplete) thread and countersunk head. Designed for joining wood and composite construction elements where a flush finish is required. Suitable for structural fastening tasks, furniture assembly and general carpentry where short countersunk screws are needed.

## Long description

Pack of 48 Koelner/Rawlplug construction screws R-S3-PTX-30020, size 3.0 x 20 mm with partial thread and countersunk head. These screws are designed for joining wood and composite construction elements where a flush finish is required. The partial thread provides clamping force while the unthreaded shank allows components to pull tightly together; the countersunk head seats flush with the surface for a neat appearance and to allow for surface treatments or coverings.
Advantages
The Koelner/Rawlplug R-S3-PTX-30020 screws come in a practical pack of 48 and combine a partial thread for improved clamping with a countersunk head for flush mounting. Their 3.0 x 20 mm dimensions make them suitable for short penetrations where secure fastening is required without protruding heads. The design reduces splitting risk in thinner wooden elements and enables a smooth finish for visible surfaces.
Suitable for
 Assembly of furniture and cabinets where countersunk heads are needed
 Joining thin wood panels, plywood or composite boards
 General carpentry and light structural fastening tasks
 Situations requiring a flush surface for painting, veneering or covering
When it may not be suitable
These screws are short (20 mm length) and have a 3.0 mm diameter; they are not appropriate for heavy structural connections or applications requiring deep penetration into thick timbers. They are also not intended for use in masonry, concrete, or metal without appropriate anchors or pilot holes and are not a substitute for longer, fully threaded fasteners where thread along the full shank is necessary.
Key specifications
 Quantity: 48 pieces per pack
 Size: 3.0 x 20 mm (diameter x length)
 Thread type: Partial (incomplete) thread
 Head type: Countersunk head for flush mounting
 Material/finish: metal construction screws (manufacturer finish as supplied)
How to use
Select an appropriate pilot hole diameter for the 3.0 mm screw and the type of wood or composite you are fastening; in many cases a pilot hole helps prevent splitting and eases installation. Drive the screw until the countersunk head is flush with the surface. Use a compatible screwdriver bit or driver to match the screw head recess and avoid cam-out. For best results, clamp workpieces before fastening and check alignment before final tightening.
What to consider before purchase
 Verify that 3.0 x 20 mm length is sufficient for material thickness and required thread engagement
 Ensure partial thread fastener is suitable for your joint type (clamping vs full-thread requirements)
 Confirm compatibility of the screw head and driver bit you plan to use
 Consider corrosion resistance needs based on indoor/outdoor use and the manufacturer's finish
Usage recommendations
Use these Koelner/Rawlplug construction screws for interior woodwork, furniture assembly and light carpentry where a flush countersunk finish is desired. For hardwoods or narrow edge connections, pre-drilling a pilot hole is recommended. Do not use for load-bearing structural connections without verifying required fastener specifications.
