What are wing-tip screws?
Wing-tip screws are specialist fixings designed for attaching timber directly to heavy section steel. The wings ream out the timber during installation, allowing the screw to spin freely without binding. Once the wings reach the steel, they break off so the thread can tap directly into the metal.
Why choose zinc wing-tip screws?
- Designed for fixing timber to steel up to 12mm thick
- Wing-tip clears timber to prevent thread binding
- Self-drilling point removes the need for pre-drilling
- Countersunk head provides a flush finish in timber
- Zinc finish suitable for internal and dry environments
How do wing-tip screws work?
Wing-tip screws feature small cutting wings above the drill point. As the screw drives through timber, the wings widen the hole slightly. This prevents the thread from gripping too early and allows the screw to reach full drilling speed.
When the screw contacts the steel, the wings snap off. The drill point then cuts into the steel, and the thread forms a secure fixing.
Where are they used?
These screws are commonly used for:
- Fixing timber battens to steel frames
- Timber to steel construction
- Roofing and cladding support structures
- General construction where timber meets steel
Available Sizes & Typical Applications
| Size | Typical Use |
|---|---|
| 5.5 x 45mm | Light timber to steel fixing |
| 5.5 x 65mm | General timber to steel applications |
| 5.5 x 85mm | Fixing thicker timber sections |
| 5.5 x 100mm | Deeper penetration into timber and steel |
| 5.5 x 120mm | Heavy-duty timber to steel fixing |
When should you use zinc wing-tip screws?
Zinc wing-tip screws are best suited for internal applications or environments with low humidity. They provide a cost-effective solution for timber to steel fixing where corrosion resistance is not the primary concern.

Frequently Asked Questions
What are wing-tip screws used for?
Wing-tip screws are used for fixing timber to steel, particularly where thicker steel sections are involved.
Do wing-tip screws need a pilot hole?
No – the self-drilling point eliminates the need for pre-drilling in both timber and steel.
Why do wing-tip screws have wings?
The wings clear out the timber as the screw drives through, preventing the thread from binding before it reaches the steel.
Can zinc wing-tip screws be used outside?
Zinc screws are best suited for internal use. For external applications, bi-metal options are recommended.
