## Long description

The Prox Wood Construction Screw measures 4.5 mm in diameter and 40 mm in length, featuring a partial thread of 25 mm. Designed for reliability and strength, this screw includes a countersunk head and a TX20 Torx drive, making it suitable for secure fastening in various wooden structures. The design helps minimize the risk of wood splitting during installation while ensuring a flush, clean finish on the surface. Each pack contains 250 pieces of these certified fasteners, manufactured according to the EN 14592 standard for structural timber products.
Advantages
This wood construction screw offers high torque transfer and reduces the likelihood of bit slip due to the reliable TX20 Torx drive. The partial thread design pulls wooden elements tightly together for a strong and stable connection. The countersunk head allows the screw to sit flush with the wood surface, eliminating the need for additional countersinking steps and preparing the material effectively for subsequent finishing. Furthermore, the specialized construction helps prevent wood from cracking, even when working close to edges.
Suitable for
Woodworking projects and furniture assembly
Timber framing and general carpentry work
Securing wooden boards and panels
Professional construction and DIY installations
When it may not be suitable
This fastener may not be suitable for heavy-duty applications requiring thicker structural timber beyond the specified dimensions. It is also not recommended for direct use in non-wooden materials such as concrete, brick, or metal without proper pre-drilling and anchors.
Key specifications
Diameter: 4.5 mm
Length: 40 mm
Thread length: 25 mm
Drive type: TX20 Torx
Head type: Countersunk
Thread type: Partial thread
Standard compliance: EN 14592
Quantity: 250 pieces per pack
How to use
Select a suitable screwdriver or power drill equipped with a TX20 bit. Align the screw perpendicular to the wood surface and drive it in at a steady speed. The partial thread will pull the top wooden board securely against the base material. Ensure the countersunk head sinks completely level with or slightly below the wood surface to achieve a smooth finish. Pre-drilling may be necessary in hard timber to prevent splitting.
What to consider before purchase
Verify that the 4.5 mm diameter and 40 mm length match the thickness of the materials being joined.
Check that a TX20 drive bit is available for your power tool.
Confirm that the partial thread length of 25 mm is adequate for your specific assembly requirements.
Usage recommendations: Store the screws in a dry environment to prevent corrosion. Always use the correct TX20 bit size to avoid damaging the screw head during high-torque driving.
