What are exterior wing-tip screws for light section steel?
Exterior wing-tip screws are designed to fix timber directly to light section steel without pre-drilling. The wing-tip design clears the timber during installation, allowing the screw to reach full drilling speed before engaging with the steel.
Why choose exterior wing-tip screws?
- Designed for fixing timber to steel up to 5mm thick
- Exterior coating provides corrosion resistance
- Wing-tip reduces resistance when passing through timber
- Self-drilling point removes the need for pre-drilling
- Countersunk head provides a flush finish
- Supplied with PH3 S2 driver bit for convenience
How do wing-tip screws work?
As the screw drives through timber, the wings cut a slightly larger hole. This allows the screw to rotate freely without the thread gripping too early.
Once the screw reaches the steel, the wings break off. The drill point then cuts into the metal, and the thread forms a secure fixing.
Where are they used?
These screws are commonly used for:
- Fixing timber battens to light gauge steel frames
- Cladding and external panel systems
- Roofing support structures
- General construction in outdoor environments
Available Sizes & Typical Applications
| Size | Typical Use |
|---|---|
| 4.2 x 38mm | Light timber to thin steel fixing |
| 4.8 x 38mm | General fixing into light gauge steel |
| 5.5 x 50mm | Timber to light steel applications |
| 5.5 x 65mm | Fixing thicker timber sections |
| 5.5 x 85mm | Deeper penetration into timber and steel |
| 5.5 x 100mm | Longer reach fixing into light steel |
When should you use exterior wing-tip screws?
Exterior wing-tip screws are the right choice for outdoor or exposed environments. The coating provides improved corrosion resistance, making them suitable for cladding, roofing, and general construction work where moisture exposure is a factor.

Frequently Asked Questions
What are exterior wing-tip screws used for?
They are used for fixing timber to steel in outdoor or exposed environments.
Do wing-tip screws need a pilot hole?
No – the self-drilling point allows them to cut into both timber and steel without pre-drilling.
What is the difference between zinc and exterior wing-tip screws?
Exterior screws have a protective coating for improved corrosion resistance, making them suitable for outdoor use.
Can these screws be used for structural applications?
They are suitable for timber to steel fixing in construction, but always check specifications for structural requirements.
