Prox Wood Construction Screw 4x45 mm TX20 Countersunk Head Partial Thread 20 pcs

The Prox Wood Construction Screw 4x45 mm TX20 Countersunk Head Partial Thread is a reliable fastening solution designed for secure wood-to-wood assembly in various construction and woodworking projects. Measuring 4 mm in diameter and 45 mm in length, this fastener features a 25 mm partial thread that ensures tight component clamping while minimizing the risk of wood splitting. Equipped with a countersunk head, it allows for a flush finish on the material surface without requiring additional countersinking work. The TX20 Torx drive enables high torque transfer and significantly reduces tool slip during installation, improving efficiency and accuracy.

Advantages

This construction screw offers high stability and reliable holding power for structural wood assemblies. The partial thread design pulls wooden components tightly together, creating strong joints. The countersunk head ensures that the fastener sits flush with or below the wood surface, providing a clean appearance suitable for visible installations. The TX20 Torx drive securely engages with the driving tool, allowing for efficient force transmission and minimizing wear on both the screw and the bit. Manufactured to meet standard requirements, it complies with EN 14592 specifications for structural timber products.

Suitable for

• Wood-to-wood assembly in construction projects
• Furniture manufacturing and repair
• General carpentry and woodworking tasks
• Installing timber frames and supports

When it may not be suitable

This product may not be suitable for heavy-duty industrial timber framing that requires larger diameter structural fasteners. It is also not recommended for direct use in highly corrosive environments or with treated lumber that reacts aggressively with standard carbon steel without proper protective coatings.

Key specifications

• Diameter: 4 mm
• Length: 45 mm
• Thread length: 25 mm
• Thread type: Partial thread
• Head type: Countersunk head
• Drive type: TX20 Torx
• Standards compliance: EN 14592
• Quantity per pack: 20 pieces

How to use

Select a compatible TX20 screwdriver bit and insert it securely into your power tool or manual driver. Align the screw perpendicular to the wood surface and drive it in at a steady speed. The partial thread will pull the top wooden piece firmly against the base material as the countersunk head sinks flush into the wood. Pre-drilling may be necessary depending on the wood density and proximity to board edges to prevent splitting.

What to consider before purchase

• Verify that the 4 mm diameter and 45 mm length are appropriate for your specific material thickness
• Ensure you have a TX20 compatible driving tool available
• Check if the 25 mm partial thread length matches your clamping requirements
• Confirm that the pack size of 20 pieces is sufficient for your project scope

Usage recommendations: Store the screws in a dry environment to prevent moisture exposure and corrosion prior to use. Always use the correct TX20 drive bit size to ensure optimal torque transfer and prevent damage to the fastener head.
