Prox Wood Construction Screw 4x60 mm Partial Thread TX20 Countersunk Head

The Prox Wood Construction Screw 4x60 mm Partial Thread TX20 Countersunk Head is engineered for secure and stable assembly in various wooden structures. Measuring 4 mm in diameter and 60 mm in total length with a 36 mm partial thread, this fastener is designed to meet demanding woodworking requirements. The countersunk head integrates smoothly into the material surface, allowing for a clean, flush finish without the need for complex pre-countersinking. Utilizing a Torx TX20 drive, the screw permits efficient torque transfer, minimizing tool slippage and installation effort. The partial thread design effectively pulls wooden elements tightly together, enhancing structural integrity while significantly lowering the risk of wood splitting.

Advantages

This wood construction screw provides high stability and strong clamping force due to its engineered partial thread configuration. The TX20 drive system ensures reliable engagement between the tool and the screw head, preventing cam-out during high-torque applications. The countersunk head design delivers a neat, flush appearance suitable for visible wooden surfaces. Additionally, the screw is compliant with the EN 14592 standard, ensuring certified quality and performance for structural timber applications.

Suitable for

• Assembly of wooden frames and internal timber structures
• Installing wooden panels, boards, and trim
• General carpentry and DIY woodworking projects
• Joining solid wood and engineered timber components

When it may not be suitable

This screw may not be appropriate for heavy-duty structural applications requiring larger diameter fasteners or in environments with high moisture levels where specialized corrosion-resistant coatings are mandatory. It is also not intended for direct fastening into masonry, concrete, or metal substrates without appropriate anchors.

Key specifications

• Dimensions: 4x60 mm
• Thread length: 36 mm
• Thread type: Partial thread
• Drive type: TX20 Torx
• Head type: Countersunk head
• Quantity per pack: 250 pieces
• Standard compliance: EN 14592

How to use

Select a compatible TX20 screwdriver bit and attach it to your power tool or manual driver. Align the wooden pieces to be joined in their desired final position. Position the screw perpendicular to the wood surface and drive it in at a steady, controlled speed. The partial thread will engage to pull the upper wooden element firmly against the lower piece. Continue driving until the countersunk head is completely flush with or slightly below the wood surface.

What to consider before purchase

• Verify that the 4x60 mm dimensions and 36 mm partial thread length match your specific material thickness.
• Ensure you have a TX20 driver bit available for installation.
• Check if the environmental conditions require specialized anti-corrosion treatments.
• Confirm that the pack size of 250 pieces aligns with the scope of your project.

Always pre-drill pilot holes when working near the edges of hard or dense timber to prevent splitting, and ensure the driver is held straight to maintain optimal torque transfer.
