Which Screw Should I Use?
Not sure what to pick? Here's a quick guide:

• Deck boards to joists – Use C2 Deck-Fix for the strongest clamp and cleanest finish
• Budget-friendly decking – Choose our standard green decking screws for softwood boards
• Coastal or wet areas – Go for stainless steel decking screws – corrosion-proof and built to last
• Heavy timber framing – Use Advanced Coach Screws or Coach Screws (Exterior)
• Timber to masonry – Pair Coach Screws or Carriage Bolts with a wall plug
• Retaining walls, sleepers, big structures – Use Timber & Landscaping Screws for full holding power

Which Screws Resist Rust the Best?
Outdoor jobs demand weather resistance. Here’s how the finishes compare:

• Zinc-Plated – Basic rust protection, best for indoor or sheltered use
• Exterior Green Coated – Tough multi-layer coating, ideal for most outdoor conditions
• Stainless Steel – No coating needed – the best choice for coastal areas, damp environments or anywhere you want zero rust

Do I Need Heavy-Duty Screws?
Not every job needs a heavy-duty fixing – but when it does, you’ll feel the difference.

• Standard Decking Screws are great for softwood boards and garden decking – quick to install and easy on the wallet
• C2 Deck-Fix Screws give more grip and a neater finish – great for composite or long-lasting decking
• Coach Screws and Timber Screws step it up for structural timber – framing, fencing, raised beds, pergolas, sleepers and more

If you're not sure, go heavier – especially in structural or high-traffic areas
