Choosing the Right Screw
Deck Boards to Joists
Use purpose-designed decking screws for secure, clean fixing with excellent corrosion resistance.
Heavy Structural Timber
Coach screws and timber & landscaping screws provide superior pull-out resistance and clamp force for larger joints, sleepers and landscaping timber.
High-Moisture or Coastal Conditions
Choose stainless steel decking screws or A4 stainless timber screws for maximum corrosion resistance in exposed environments.
Neater, Low-Profile Finishes
Wafer head timber screws distribute load evenly while sitting lower in the timber surface - ideal where appearance matters.
Head Type Comparison
| Head Type | Best For | Key Benefit |
|---|---|---|
| Cylinder/TX Decking | Deck boards | Clean finish & strong clamp |
| Coach Head | Heavy timber framing | Maximum holding & structural strength |
| Hex Head | Structural & landscaping | High torque & strong clamping |
| Wafer Head | Visible faces & neat finishes | Wide bearing & low profile |
Finish Comparison (Corrosion Resistance)
| Finish | Best For | Corrosion Protection |
|---|---|---|
| Zinc Plated | Indoor & sheltered uses | Basic protection |
| Exterior Green/Silver | General outdoor timber | Strong outdoor protection |
| Stainless Steel (A2) | External environments | High corrosion resistance |

What Size Should You Use?
As a practical guide, choose a screw that penetrates 2–3× the thickness of the material being fixed into the base timber.
