Prox Wood Construction Screw 3.5x45 mm Partial Thread Countersunk Head TX15 20 pcs

The Prox Wood Construction Screw measures 3.5x45 mm and features a 25 mm partial thread, a countersunk head, and a TX15 Torx drive. This wood construction screw is specifically engineered for secure and stable timber connections across various construction and assembly projects. The countersunk head design allows the fastener to sink flush with the wood surface for a clean finish, while minimizing the risk of wood splitting during installation. The partial thread helps draw joined pieces tightly together, and the TX15 drive enables efficient torque transfer with reduced risk of bit slip. Manufactured in compliance with the EN 14592 standard, each package contains 20 pieces.

Advantages

The design of the Prox wood construction screw incorporates a partial thread that ensures timber elements are pulled firmly together for a tight joint. Its countersunk head allows for a completely flush surface finish without requiring complex pre-sinking work. The TX15 Torx drive facilitates high torque transmission, preventing the drive tool from slipping out and extending the lifespan of both the screw and the bit. Additionally, the screw geometry minimizes the natural tendency of wood to split near edges, making it reliable for precision joinery and general framing.

Suitable for

• General timber construction and framing
• Assembly of wooden furniture and fixtures
• Interior renovation and joinery tasks
• Securing wooden panels and trim work

When it may not be suitable

This fastener may not be suitable for heavy-duty structural load-bearing timber applications that require thicker diameter fasteners. It is also not recommended for direct use in highly corrosive environments or with treated lumber that requires specialized corrosion-resistant coatings unless additional protective measures are taken.

Key specifications

• Dimensions: 3.5 mm diameter and 45 mm length
• Thread length: 25 mm partial thread
• Head type: Countersunk head
• Drive type: TX15 Torx
• Standard compliance: EN 14592
• Quantity: 20 pieces per package

How to use

Select an appropriate power driver equipped with a TX15 Torx bit to match the fastener head. Position the timber elements securely before driving the screw straight into the wood. Pre-drilling may be beneficial in dense hardwoods to ensure optimal placement and to prevent surface damage, even though the screw is designed to reduce splitting. Drive the fastener at a steady speed until the countersunk head rests flush with or slightly below the timber surface.

What to consider before purchase

• Verify that the 3.5 mm diameter and 45 mm length are appropriate for your specific timber thickness
• Ensure you have a compatible TX15 screwdriver bit available
• Calculate the total quantity needed, keeping in mind that each pack contains 20 pieces

Usage recommendations

For best results when installing the Prox wood construction screw, use a compatible TX15 bit and maintain a steady, controlled pressure during driving to achieve a flush finish without stripping the recess.
