Prox Wood Construction Screw 4.5x50 mm Partial Thread Torx TX20 Countersunk Head 250 pcs

The Prox Wood Construction Screw measuring 4.5x50 mm with a 30 mm partial thread, countersunk head, and Torx TX20 drive is designed for secure and stable assembly in various wooden structures. This screw ensures a reliable connection for carpentry and construction projects while minimizing the risk of wood splitting during installation.

Advantages

The partial thread design allows wooden elements to be pulled tightly together for a strong and durable joint. The countersunk head sinks flush into the material, creating a smooth surface finish without requiring complex preliminary countersinking. Equipped with a Torx TX20 drive, the screw allows for high torque transfer and significantly reduces bit slip during driving, resulting in efficient and precise installation. Manufactured to conform with standard EN 14592, it meets established requirements for structural timber fasteners.

Suitable for

• Assembly of wooden structures and frames
• General carpentry and woodworking projects
• Joining timber elements securely with a flush finish

When it may not be suitable

This product may not be suitable for heavy-duty load-bearing applications in engineered timber that require specialized structural bolts or larger diameter fasteners. It is also not intended for direct use in masonry, concrete, or metal substrates without appropriate anchors.

Key specifications

• Dimensions: 4.5 mm diameter by 50 mm length
• Thread length: 30 mm partial thread
• Drive type: Torx TX20
• Head type: Countersunk head
• Standard compliance: EN 14592
• Quantity: 250 pieces per pack

How to use

Select an appropriate screwdriver or power drill equipped with a Torx TX20 bit. Position the wooden elements to be joined and drive the screw perpendicularly into the wood surface until the countersunk head sits flush with or slightly below the material. For optimal results in hard woods, pre-drilling a pilot hole is recommended to prevent damage and ensure precise alignment.

What to consider before purchase

• Verify that the 4.5x50 mm dimensions and 30 mm partial thread match the thickness of the materials being joined.
• Ensure a Torx TX20 driver bit is available for installation.
• Check that the pack size of 250 pieces is sufficient for the intended scope of work.

Usage recommendations

For best performance, use a compatible TX20 bit at a controlled speed to avoid stripping the drive recess, and store the screws in a dry environment to maintain their material integrity.
