Structural Construction TORX Screws for Wood
Technical and Application Details
Professional screws for structural fastenings in wood
TX structural screws for wood have been developed for demanding applications where reliability, consistency, and load capacity are essential. Unlike decorative or light-duty screws, structural screws are designed to withstand high torque, deep penetration, and long-term loads in wood-to-wood connections.
Suitable for both construction contractors and demanding DIY users who need predictable performance on site.
Why choose structural wood screws?
- Certified for structural use
Fabricated in accordance with standards for structural timber connections. - TORX Drive
Optimal torque transmission, reduced cam-out and minimizes head damage. - High-strength tempered steel
Reduced risk of breakage during installation, even in dense or hard wood. - Consistent manufacturing quality
Uniform geometry and material properties across batches for predictable results. - Clean, fast and precise penetration
Optimized thread for fast driving and high tention capacity. - Long-term connection reliability
Maintaing clamping force over time in structural assemblies.
Countersunk vs flangehead
- The choice of connector type influences the finish and performance of the connection.
- The countersunk head allows the screw to sit flush with the wood surface, providing a clean finish and facilitating the application of overlapping pieces. It is recommended when a recessed head is required.
- The flanged head (disc/washer type) offers a larger support area and distributes pressure better over surface of the wood, increasing clamping capacity and reducing the risk of the head sinking into the wood. It is especially suitable for structural connections where greater strength and clamping force are desired.
Typical use
These structural bolts are typically used in:
Roof structures and trusses
Pergolas and outdoor wooden structures
Deck substructures
Timber structures and load-bearing beams
Timber framed houses
Reinforcement and reconstruction of timber structures.
If your project requires high fastening strength and structural integrity, this type of screw is the right choice.
Who are they suitable for?
Recommended for:
Construction companies
Carpenters and timber framing companies
Deck, pergola and roof installers
DIY users with structural projects
Not necessary for:
Decorative applications
Lightweight interior fixings
Furniture assembly
Construction screws are intended for structural use, where safety and performance are critical.
Advantages over standard DIY screws
Greater torque resistance
Redcuced risk of screw head damage
Highe holding, load capacity
Consistent quality
Designed for structural loads
While standard DIY screws may be cheaper, they are not designed to withstand the demands of construction.
How to choose the correct size
Proper selection of diameter and length is fundamental to structural performance.
General guidelines:
Length:
The screw length should be at least 2 to 3 times the thickness of the fastened part of the timber.
Diameter:
Larger diameters offer greater load capacity and are recommended for structural connections. For high-load structural connections, we recommend bolts with a diameter of 6mm, 8mm or 10mm.
Type of the wood
Hardwoods may require larger diameters and pre-drilling.
If you have any questions, our team can recommend the appropriate sizes for your project.
