## Long description

Prox wood construction screw with a diameter of 4.5 mm, length of 40 mm, and a 25 mm partial thread designed for secure and stable wood-to-wood assembly in various construction tasks. These fasteners feature a countersunk head for a flush finish and a TX20 Torx drive for high torque transmission and reduced slip, conforming to the EN 14592 standard for structural timber fasteners.
Advantages
The partial thread design helps ensure tight drawing together of wooden elements during installation while minimizing wood splitting. The countersunk head allows the screw to sink fully into the material for a smooth surface finish. Additionally, the TX20 Torx drive facilitates efficient power transfer and prevents bit slippage.
Suitable for
Wood-to-wood assembly and construction tasks
Securing timber elements requiring a flush surface finish
General carpentry and building projects
When it may not be suitable
This product may not be suitable for heavy-duty industrial metal framing or masonry applications where specialized anchors are required. It is also not intended for extremely thick wooden beams that require longer fasteners exceeding 40 mm in length.
Key specifications
Diameter: 4.5 mm
Length: 40 mm
Thread length: 25 mm
Drive type: TX20 Torx
Head type: Countersunk
Quantity per pack: 18 pieces
Standard compliance: EN 14592
How to use
Align the wooden components to be joined and select a compatible TX20 screwdriver bit. Insert the screw into the wood and drive it in steadily until the countersunk head is flush with the surface. Pre-drilling may be performed if working near the edges of hard timber to further prevent splitting.
What to consider before purchase
Verify that the 4.5 mm diameter and 40 mm length meet the dimensional requirements of your project
Ensure you have a TX20 driver bit available
Check that the 18-piece pack quantity is sufficient for your planned tasks
Usage recommendations: Store the screws in a dry environment to prevent corrosion before installation and always use the correct TX20 bit size to maintain optimal torque transfer and avoid tool wear.
