Prox Wood Construction Screw 3.5x50mm TX15 Countersunk Head Partial Thread 15pcs

The Prox Wood Construction Screw 3.5x50mm TX15 Countersunk Head Partial Thread 15pcs is a precision-engineered timber fastener designed for reliable and secure wood assembly. Measuring 3.5 mm in diameter and 50 mm in length with a 30 mm partial thread, this screw combines a countersunk head for a flush finish with a Torx TX15 drive for efficient torque transfer. Certified to EN 14592, it is suitable for various professional and general woodworking, carpentry, and construction projects, offering dependable joint clamping and reduced risk of wood splitting.

Advantages

This construction screw features a partial thread design that pulls wooden elements tightly together for a strong and durable joint. The countersunk head allows the fastener to sink flush into the material surface without requiring extra countersinking work. Equipped with a TX15 Torx drive, it ensures stable tool engagement, prevents cam-out, and allows higher torque application compared to standard drives. The geometry of the screw minimizes wood splitting, while its compliance with EN 14592 guarantees certified reliability for structural timber applications.

Suitable for

• General woodworking and carpentry tasks
• Timber construction and assembly projects
• Securing panels, battens, and wooden frames
• Professional building applications requiring EN 14592 certified fasteners

When it may not be suitable

This screw may not be suitable for heavy-duty structural timber connections that require larger diameters or longer lengths than 3.5x50 mm. It is also not intended for direct use in masonry, concrete, or metal framing without appropriate anchors.

Key specifications

• Dimensions: 3.5 mm diameter x 50 mm length
• Thread length: 30 mm partial thread
• Drive type: TX15 Torx
• Head type: Countersunk head
• Standard compliance: EN 14592
• Quantity: 15 pieces per pack

How to use

Align the wooden components to be joined in the desired position. Place the countersunk screw perpendicular to the wood surface and engage the TX15 driver bit securely into the screw head. Drive the fastener in with a compatible power tool or screwdriver until the countersunk head sits flush with or slightly below the wood surface. The partial thread will draw the top board firmly against the base material.

What to consider before purchase

• Verify that the 3.5x50 mm dimensions match the thickness and load requirements of your timber materials.
• Ensure you have a compatible TX15 screwdriver bit or power tool attachment.
• Check the required quantity for your project, as this package contains 15 pieces.

Usage recommendations

Use appropriate torque settings on your power tool to avoid stripping the screw head or over-tightening into soft wood materials. For optimal results in dense timber, ensure proper alignment before driving the fastener.
