Winged Cutters (Milling Wings) – For Stress-Free, Clean and Precise Fastening
:quality(80))
When fastening wood-to-wood or wood-to-metal, materials can unintentionally come under tension. This may lead to cracking, deformation, or a less refined finish. That’s why many of our screws are equipped with winged cutters — also known as milling wings. This smart addition makes the difference between a standard installation and a professional, stress-free connection.
What exactly do winged cutters do?
Winged cutters are small protrusions on the screw shank. As the screw is driven in, they mill a slightly larger hole in the top layer of material. This gives the upper panel just enough extra space to sit neatly against the material underneath.
The result:
No tension in the panel
Reduced risk of splitting or deformation
A cleaner, more precise final appearance
Improved fit when installing façade panels, timber structures and more
Once the wings reach the lower material layer, they automatically break off, allowing the screw to bite firmly into the substrate.
When should you choose a screw with winged cutters?
Screws with winged cutters are ideal in situations where you want to prevent two materials from being pulled together too tightly — which can cause damage or tension build-up. They are especially used for:
Façade cladding on timber or metal substructures
Wood-to-wood connections with differences in board thickness
Applications where a visible, clean finish is important
Panels and boards that are sensitive to tension
By using winged cutters, the panel remains nicely level, and the construction maintains its shape.
Advantages of screws with winged cutters
Faster installation without additional tools
Stress-free fastening of panels
Reduced risk of damage such as splitting or warping
Clean, precise finishing — ideal for exposed surfaces
Automatic break-off of the wings, ensuring strong anchoring in the second material
