Wing-Tip Screws for Timber to Light Section Steel

Wing-tip screws, also known as wood to metal screws, are designed for fixing timber to light section steel up to 5mm without pre-drilling.

What are wing-tip screws for light section steel?

Wing-tip screws are specialist fixings used to attach timber directly to thinner steel sections. The wing-tip design clears the timber during installation, allowing the screw to drill efficiently into the steel without binding.

Why use wing-tip screws?

  • Designed for fixing timber to steel up to 5mm thick
  • Wing-tip clears timber to prevent thread binding
  • Self-drilling point removes the need for pre-drilling
  • Countersunk head provides a flush finish
  • Fast and efficient installation for timber to metal fixing

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 and reach full drilling speed.

When the screw reaches the steel, the wings snap off. The drill point then cuts into the metal, and the thread forms a secure fixing.

Zinc vs exterior vs bi-metal wing-tip screws

Choosing the right finish depends on the environment and level of corrosion resistance required:

Type Corrosion Resistance Best For When to Choose
Zinc Wing-Tip Screws Low Internal and dry environments Use when corrosion is not a concern and cost efficiency is important
Exterior Wing-Tip Screws Medium Outdoor use with moderate exposure Use for cladding and general external construction
Bi-Metal Wing-Tip Screws High Exposed, industrial, or higher moisture environments Use when durability and corrosion resistance are critical

Where are wood to metal screws used?

Wing-tip screws are commonly used for:

  • Fixing timber battens to light gauge steel frames
  • Drylining and partition systems
  • Cladding support structures
  • General construction where timber meets steel

Frequently Asked Questions

What are wing-tip screws used for?
Wing-tip screws are used for fixing timber to steel, particularly where light section steel is used.

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 light and heavy section wing-tip screws?
Light section screws are designed for thinner steel, typically up to 5mm, while heavy section screws are used for thicker steel up to 12mm.

What is a wood to metal screw?
A wood to metal screw is designed to fix timber directly to steel. Wing-tip screws are a specialised type that prevents binding in timber during installation.

Which wing-tip screws should I choose?
Choose zinc for internal use, exterior for general outdoor work, and bi-metal for higher corrosion environments.
