Prox Wood Construction Screw 4.5x80/50 mm TX20 Countersunk Partial Thread 25 pcs

The Prox Wood Construction Screw measuring 4.5x80 mm with a 50 mm partial thread, countersunk head, and TX20 drive is designed for secure and stable timber assembly and general construction work. This wood construction screw features a Torx drive for high torque transfer and reduced cam-out, partial threading for tight joint pull-down, and anti-splitting geometry that helps protect timber during installation. Conforms to EN 14592 standards for structural timber fasteners and is supplied in a convenient pack of 25 pieces.

Advantages

This wood construction screw offers reliable performance through its specialized design features. The countersunk head allows the screw to sit flush with the wooden surface, creating a smooth finish without requiring additional countersinking work. The Torx TX20 drive ensures efficient power transmission from the tool to the fastener, minimizing the risk of slipping and extending the lifespan of the driving bits. Furthermore, the partial thread design effectively pulls wooden elements together for a tight and secure joint, while the integrated anti-splitting geometry prevents the wood from cracking under pressure.

Suitable for

• Timber framing and general wood construction
• Assembling wooden furniture and fixtures
• Securing decking, battens, and boards
• General carpentry and renovation tasks

When it may not be suitable

This product may not be suitable for heavy-duty industrial applications requiring larger diameter fasteners or for use with metal and masonry substrates without appropriate anchors. It is also not recommended for highly corrosive environments unless made from specialized stainless steel grades.

How to use

Select a suitable power drill or screwdriver equipped with a TX20 bit. Align the wood construction screw perpendicularly to the timber surface. Apply steady pressure and operate the tool at a moderate speed to drive the screw into the material until the countersunk head is flush with the surface. Pre-drilling may be necessary depending on the wood density and proximity to board edges to ensure optimal installation results.

What to consider before purchase

• Verify that the 4.5 mm diameter and 80 mm length match your specific timber thickness requirements
• Ensure you have a compatible TX20 screwdriver bit for installation
• Check the pack quantity of 25 pieces to ensure it meets the volume needed for your project
• Confirm that the application involves wooden substrates complying with standard timber construction requirements

Usage recommendations

For best results in wood construction, ensure the correct alignment of components before driving the screw and use a properly fitted TX20 bit to prevent wear. Pre-drilling dense hardwoods is recommended to maintain joint integrity and prevent structural damage.
