Countersunk C2 Strong Fix Wood Screws – Yellow Zinc, PZ Drive
6.0mm Diameter – Deep structural screws for secure timber fastening
These heavy-duty 6.0mm C2 Strong-Fix screws are designed for demanding structural timber applications.

Each screw is wax lubricated for smoother insertion and reduced torque.
Perfect for outdoor frames, heavy joists, timber sleepers, and structural connections where size and strength matter.
Key Features
- Double countersunk head reduces shear and sits flush
- Twin-cut tip ensures rapid start and prevents timber splitting
