## Long description

The Prox Wood Construction Screw 4x50 mm Partial Thread TX20 Countersunk Head 15 pcs is a specialized fastener designed for secure and stable assembly in wooden structures and various construction works. With a diameter of 4 mm and a length of 50 mm, this screw features a 25 mm partial thread that ensures tight joint clamping between wooden elements. The countersunk head allows the screw to sit flush with the material surface for a clean, professional finish. Equipped with a TX20 Torx drive, it enables higher torque transfer and effectively prevents bit slip during installation. Conforming to the EN 14592 standard for structural timber fasteners, this product is supplied in a convenient pack of 15 pieces.
Advantages
The partial thread design pulls wooden components tightly together, creating a robust and stable connection. The countersunk head sinks completely into the wood, providing a smooth surface without requiring additional countersinking steps. The Torx TX20 drive system facilitates efficient power transmission, reducing wear on both the tool and the screw head while minimizing slip. Additionally, the screw construction helps minimize the risk of wood splitting during insertion.
Suitable for
Assembly of wooden structures and timber framing
General construction and carpentry works
Securing wooden panels and boards
Indoor and outdoor wood-to-wood fastening projects
When it may not be suitable
This screw is not designed for heavy-duty metal-to-metal fastening or direct masonry applications without appropriate anchors. It may also be unsuitable for extremely thick timber beams that require longer fasteners than the provided 50 mm length.
Key specifications
Diameter: 4 mm
Length: 50 mm
Thread length: 25 mm partial thread
Drive type: TX20 Torx
Head type: Countersunk
Standard conformity: EN 14592
Quantity per pack: 15 pieces
How to use
Select a compatible TX20 screwdriver bit and insert the screw into the designated wooden surface. Align the components to be joined, ensuring the partial thread will engage the connecting piece while the unthreaded shank passes through the top piece. Drive the screw straight into the wood at a moderate, steady speed until the countersunk head is completely flush with the surface. Pre-drilling may be required depending on the wood density to prevent splitting.
What to consider before purchase
Verify that the 50 mm length and 4 mm diameter match the requirements of your specific woodworking project
Ensure you have a compatible TX20 screwdriver bit or driver available
Check the wood thickness to ensure the 25 mm partial thread provides adequate clamping force
Usage recommendations: Always use appropriate personal protective equipment during installation. Store the screws in a dry environment to prevent corrosion before use.
