Prox Wood Construction Screw 5x80 mm TX25 Countersunk Head Partial Thread 250 pcs

The Prox Wood Construction Screw 5x80 mm TX25 Countersunk Head Partial Thread 250 pcs is a professional-grade fastener engineered for reliable and stable assembly in various wooden structures. Measuring 5 mm in diameter and 80 mm in length with a 50 mm partial thread, this construction screw provides exceptional holding power for timber framing and general carpentry work. Featuring a Torx TX25 drive, it allows for high torque transfer without bit slippage, ensuring efficient and smooth driving during installation. The partial thread design pulls wooden components tightly together for a secure joint, while the countersunk head sits flush with the wood surface without requiring pre-countersinking.

Advantages

This wood construction screw offers superior performance through its specialized partial thread, which effectively clamps materials together to prevent gaps in structural joints. The TX25 drive significantly reduces cam-out, protecting the screw head and extending the life of driving bits. The integrated countersunk head ensures a clean, flush finish suitable for visible wooden surfaces. Manufactured to comply with the EN 14592 standard, these screws guarantee certified quality and safety for load-bearing timber applications. The optimized screw geometry helps minimize wood splitting, reducing the need for pre-drilling in many standard applications.

Suitable for

• Assembly of wooden structures and timber framing
• General carpentry and woodworking projects
• Installing floorboards and decking components
• Building outdoor wooden furniture and sheds

When it may not be suitable

This product is not recommended for fastening into concrete, brick, metal, or other non-wooden masonry materials without appropriate anchors. It may also be unsuitable for extremely dense hardwoods where pre-drilling is mandatory to prevent fastener breakage, or for marine environments where specialized corrosion-resistant coatings beyond standard fasteners are required.

Key specifications

• Diameter: 5 mm
• Length: 80 mm
• Thread length: 50 mm
• Drive type: TX25 Torx
• Head type: Countersunk
• Thread type: Partial thread
• Standard compliance: EN 14592
• Quantity per package: 250 pieces

How to use

Select an appropriate impact driver or drill equipped with a TX25 Torx bit. Align the wooden components to be joined and position the screw perpendicularly to the wood surface. Apply steady downward pressure while operating the tool at medium speed to drive the screw into the timber. Continue driving until the countersunk head is completely flush with the surrounding wood surface. For dense woods or close proximity to board edges, pre-drilling a pilot hole is recommended to prevent material splitting.

What to consider before purchase

• Verify that the 5 mm diameter and 80 mm length match the thickness of the materials being fastened
• Ensure you have a compatible TX25 Torx driver bit for installation
• Check the wood type to determine if pre-drilling is necessary
• Evaluate the required quantity against the 250-piece package size to ensure project completion

Usage recommendations

Always store the screws in a dry indoor environment to prevent premature corrosion before installation, and use appropriate personal protective equipment including safety glasses while driving fasteners into wood.
