Timco Wing-Tip Screws for Timber to Light Steel – 5.5mm x 85mm – Countersunk – Self-Drilling – Exterior – Box of 100

85mm wing tip screws for timber to light steel fix timber directly into steel sections up to 5mm thick. They provide a strong and reliable fixing, so you do not need to pre-drill.

The wing-tip design clears the timber as the screw drives through. As a result, the screw rotates freely and reaches full drilling speed without the thread binding in the wood.

When the screw reaches the steel, the wings break off. The self-drilling point then cuts into the metal, and the thread forms a secure fixing.

These screws are fully threaded, so they provide consistent grip throughout the fixing. Therefore, they are well suited to thicker timber sections where a deeper fixing is required.

The exterior coating provides improved corrosion resistance. This helps protect the fixing in outdoor or exposed environments.

They feature a countersunk head with ribs. This allows the screw to sit flush into the timber and gives a clean finish.
