Prox Wood Construction Screw 5x70 mm TX25 Countersunk Head Partial Thread 20 pcs

The Prox Wood Construction Screw 5x70 mm TX25 Countersunk Head Partial Thread 20 pcs is engineered for secure and stable joints in wooden structures and general building works. These wood construction screws feature a partial thread design that ensures tight component clamping, while the countersunk head allows for a completely flush finish with the wooden surface. Built to meet the EN 14592 standard, these screws help prevent wood splitting during installation, making them a reliable choice for professional and DIY projects alike. Each box contains 20 pieces, supplied conveniently for smaller tasks or testing applications.

Advantages

Prox wood construction screws provide exceptional holding power and structural stability thanks to their precise engineering. The inclusion of a TX25 Torx drive allows for high torque transmission without cam-out, significantly reducing slip and tool wear during driving. The partial thread length of 40 mm pulls timber components tightly together for a solid connection. Furthermore, the specialized head geometry allows the screw to sink smoothly into the wood without requiring pre-countersinking, saving time and effort on the job site.

Suitable for

• Assembly of wooden frames and structures
• General carpentry and woodworking projects
• Joining timber beams and boards
• Installing wooden panels and decking subframes

When it may not be suitable

These screws may not be suitable for heavy-duty structural applications requiring larger diameter fasteners or for use with dense masonry and concrete without appropriate wall plugs. They are also not recommended for highly corrosive environments unless paired with specialized surface treatments.

How to use

To use the Prox wood construction screw, first ensure that the wood pieces to be joined are properly aligned and clamped. Select a compatible TX25 screwdriver bit and insert it securely into your power drill or driver. Position the screw perpendicular to the wood surface and drive it in at a steady speed. The partial thread will pull the top wooden component tightly against the base material as the countersunk head sinks level with or slightly below the surface of the wood. Pre-drilling may be necessary near the edges of hardwood to prevent splitting.

What to consider before purchase

• Verify that the 5 mm diameter and 70 mm length match the thickness of the timber materials you plan to fasten
• Ensure you have a compatible TX25 Torx driver bit available for your tool
• Check the quantity of 20 pieces against the total scope of your project
• Confirm that the partial thread length of 40 mm is appropriate for your specific board thickness

Usage recommendations: Always use the correct TX25 driver bit to prevent damage to the fastener head. Store the screws in a dry environment to protect them from moisture and corrosion prior to installation.
