SPAX WIROX C4 T-STAR Plus Cylinder Head Decking Screws
High-performance decking screws designed for timber decking and external wood fixings. WIROX C4 coating provides corrosion protection for outdoor use, while the cylindrical head allows for a neat, low-profile finish.
Key features
• WIROX C4 coated steel for corrosion resistance in external applications
• Cylinder head design for discreet, near-flush finish in decking boards
• T-STAR Plus drive for secure bit engagement and efficient torque transfer
• 4CUT point reduces splitting and improves penetration into timber
• Serrated thread lowers driving resistance and speeds up installation
• Fixing thread helps hold decking boards firmly in place over time
• 4.5mm diameter and 60mm length suited to standard decking applications
• Supplied in tubs of 250
Typical applications
• Timber decking installation
• Deck boards to timber joists
• Garden structures and outdoor timber work
• Pergolas, fencing and cladding
• General exterior timber fixing where a neat finish is required
Practical benefits
These screws are designed to give a clean finish while maintaining a strong hold in timber decking. The cylindrical head sits neatly into the board without the wide surface spread of traditional countersunk heads, making them suitable for visible decking areas.
The WIROX C4 coating provides reliable protection for outdoor use in non-aggressive environments. The 4CUT point and serrated thread reduce installation effort, allowing faster driving with less splitting, particularly when working close to edges.
The T-STAR Plus drive ensures consistent engagement with the bit, helping reduce cam-out and improving efficiency on site.
What is a cylinder head decking screw?
A cylinder head screw has a smaller head profile than a standard countersunk screw, allowing it to sit neatly within the timber for a less visible finish.
What is WIROX C4 coating?
WIROX is a corrosion-resistant coating designed for outdoor use. C4 classification indicates suitability for external environments with moderate exposure.
Do these screws need pre-drilling?
In most softwood decking, pre-drilling is not required. For hardwood decking or boards close to edges, pilot holes are recommended.
What is T-STAR Plus?
T-STAR Plus is SPAX’s Torx-style drive system, designed to improve bit grip and reduce slipping during installation.
Are these suitable for all decking?
They are suitable for most timber decking applications. For highly exposed or coastal environments, stainless steel screws are typically recommended.
