Prox Wood Construction Screw 5x90 mm TX25 Countersunk Head Partial Thread 20 pcs

The Prox Wood Construction Screw 5x90 mm TX25 Countersunk Head Partial Thread 20 pcs is designed for secure and stable wooden structure assembly. With a diameter of 5 mm, a length of 90 mm, and a partial thread length of 54 mm, this wood construction screw is manufactured to meet demanding carpentry and building requirements. Each screw features a countersunk head that allows for a flush finish with the wooden surface, eliminating the need for extra countersinking work. The TX25 Torx drive enables efficient high torque transfer while significantly reducing the risk of bit slippage during installation. Compliant with EN 14592 standards, this fastener ensures reliable performance in professional and DIY woodworking projects alike.

Advantages

This wood construction screw offers exceptional reliability due to its engineered partial thread design, which pulls wooden elements tightly together for a robust connection. The specialized geometry of the screw minimizes the risk of wood splitting, even when working near board edges or with dense timber. The TX25 drive recess provides a secure grip for power tools, ensuring smooth driving and preventing cam-out. Additionally, the countersunk head sinks completely into the material to create an aesthetically pleasing, smooth surface ready for subsequent finishing or painting.

Suitable for

• Assembly of wooden framing and structural timber elements
• General carpentry and woodworking projects
• Fastening boards, panels, and beams
• Outdoor and indoor wooden constructions requiring EN 14592 compliance

When it may not be suitable

This screw may not be suitable for applications involving non-wooden materials such as masonry, concrete, or structural steel without appropriate anchors. It is also not recommended for use in highly corrosive environments where specialized corrosion-resistant coatings are strictly required.

Key specifications

• Length: 90 mm
• Thread length: 54 mm
• Head type: Countersunk head
• Drive type: TX25 Torx

How to use

To use the Prox wood construction screw, select a compatible TX25 screwdriver bit and insert it firmly into the screw drive. Position the screw perpendicularly against the wooden surface. Apply steady downward pressure while operating the power tool at a moderate speed to drive the screw into the material. The partial thread will draw the two pieces of wood securely together as the countersunk head sinks flush with the surface.

What to consider before purchase

• Verify that the 5x90 mm dimensions and 54 mm partial thread length match the thickness of the materials being joined
• Ensure you have a compatible TX25 drive bit for your screwdriver or drill
• Check the pack quantity of 20 pieces to determine if additional packs are needed for your project scale

Usage recommendations: Always pre-drill pilot holes when working with hard timber species to prevent splitting and ensure optimal fastener placement. Store the screws in a dry environment to maintain their structural integrity before use.
