C2 Clamp-Fix TX Woodscrews – Superior Clamping for Structural Timber
Heavy-duty yellow zinc woodscrews engineered for structural fixings in dense timber, ideal for professional trades tackling the toughest jobs.
Engineered for Maximum Clamping. Trusted by UK Trades.
The C2 Clamp-Fix TX Woodscrews (6.0mm diameter) deliver maximum clamping force with a twin-cut tip, reinforced countersunk head, and TX drive for high-torque applications. Perfect for heavy framing, timber structures, roofing, fencing, and large joinery work where stronger screws and deeper penetration are critical.
Trusted by UK trades, these screws reduce splitting, improve pull-out resistance, and save time on site. View our full range of woodscrews for additional options.
Why Choose 6.0mm Screws?
Use 6.0mm screws when working with thick or load-bearing timber, large beams, heavy-duty framing, structural roofing, or fencing. Their wider diameter increases clamping force, shear strength, and pull-out resistance — giving superior performance for structural joinery, outdoor framing, and projects under high stress.
Key Features
- Yellow zinc passivated coating for corrosion protection in internal environments
- Twin-cut tip for fast penetration and reduced splitting
- Double countersunk head with ribs ensures flush finishing
- TX drive (star drive) improves grip, reduces cam-out under high torque
- UK CA approved certified for structural timber applications

Common Questions About Clamp-Fix Screws
Clamp-Fix screws are designed for heavy-duty internal joinery and structural timber fixings where maximum clamping and strength are needed — such as roofing joists, garden buildings, large studwork, and outdoor framing.
The twin-cut tip reduces pre-drilling in softwoods, but pre-drilling is recommended for hardwoods, dense timbers, or critical structural applications.
TX (star) drive improves grip, reduces driver slip, and allows higher torque transfer — essential for large screws driven into dense materials.
Clamp-Fix screws deliver stronger clamping and higher holding power than standard woodscrews. Their twin-cut tip, reinforced countersunk head, and TX drive provide superior grip, less splitting, and faster installs — ideal for structural timber, large framing, and heavy joinery.
