Available in four sizes from 4.5 x 50mm to 5.0 x 100mm, each screw carries a green organic coating rated to 1,000 hours of salt spray resistance.
Specifications
| Property | Detail |
|---|---|
| Drive Type | Pozi |
| Treatment | Green organic coating |
| Corrosion Resistance | Up to 1,000 hours salt spray |
| Thread | Partial thread on lengths 65mm and above (prevents timber jacking) |
| Available Sizes | 4.5 x 50mm, 4.5 x 65mm, 5.0 x 75mm, 5.0 x 100mm |
| Pack Sizes | Box of 100 or Box of 200 depending on size |
| Intended Use | External timber, decking, fencing, landscaping |
What it's used for
- Fixing deck boards to joists on garden and commercial decking projects
- Securing fence rails, pales, and feather-edge boards to fence posts
- Assembling shed frames, pergolas, and other outdoor timber structures
- Landscape construction including raised beds, sleeper walls, and timber edging
Fitting and handling
Where possible, allow deck boards to acclimatise on site for 48 hours before fixing so the timber settles to ambient moisture conditions and reduces the risk of cupping or gapping after installation. Use a cordless drill with a Pozi bit at a consistent angle, and on hardwoods or dense treated timbers consider pre-drilling to avoid splitting at board ends. Store unused screws in a dry location to preserve the organic coating.
FAQ
Why do decking screws have a partial thread rather than a full thread?
A partial thread, used on lengths of 65mm and above, grips only the lower joist rather than both boards at once. This pulls the top board tight against the joist and prevents timber jacking, where two boards are held apart creating a gap or raised surface.
Are these screws suitable for pressure-treated timber?
Yes. The green organic coating provides up to 1,000 hours of salt spray resistance, making these screws compatible with standard pressure-treated softwood decking and fencing. For highly aggressive environments or prolonged contact with modified timbers, a stainless steel fixing may be worth considering.
Which size decking screw should I use for standard 28mm deck boards?
For 28mm thick deck boards fixed to 47mm joists, the 5.0 x 75mm screw is a practical choice, giving sufficient thread engagement into the joist without breaking through the underside. The 5.0 x 100mm option suits thicker boards or double-joist details at frame ends.
