12mm Structural Timber Screws – Paneltwistec AG Heavy Duty Wood Construction Screws for CLT, Glulam & Mass Timber Engineering

Heavy Duty 12mm Timber Screws for Structural Wood Construction

The Paneltwistec AG 12mm structural timber screw is a premium heavy-duty fixing solution designed specifically for large timber structures, engineered wood systems, and high-load timber construction applications.

Manufactured from hardened carbon steel with a high-performance blue galvanised coating, the 12mm Paneltwistec screw delivers exceptional structural strength, superior pull-out performance, and reliable fixing in demanding timber engineering environments.

Designed with a specialised cutting tip and milling ribs above the thread, these 12mm wood construction screws significantly reduce driving torque and minimise timber splitting during installation, even in dense engineered timber products.

Perfect for Cross Laminated Timber (CLT), glulam beams, mass timber construction, SIP systems, heavy carpentry, timber framing, and modular timber buildings.

Why Choose 12mm Structural Timber Screws?

When maximum structural performance is required, 12mm timber screws provide the strength and stability needed for modern timber engineering.

The larger 12mm diameter offers:

• Increased structural load capacity
• Superior pull-out resistance
• Stronger timber-to-timber connections
• Improved performance in engineered timber
• Reliable fixing in large cross sections
• Enhanced stability in mass timber structures
• Reduced movement in structural assemblies

These benefits make 12mm structural screws ideal for demanding applications in commercial timber construction and heavy-duty wood engineering.

Applications for 12mm Timber Construction Screws

Cross Laminated Timber (CLT)

The Paneltwistec AG 12mm screw is widely used in CLT construction for securing large timber panels and structural timber assemblies in modern mass timber buildings.

Glulam & Engineered Timber
