Details

Application Areas:

Fastening wooden materials to metal substructures

Installation outdoors or in damp rooms

For coastal regions (offshore - salty air) or industrial applications (low level of chlorides, sulfur dioxide)

Advantages:

  • Fast and cost-efficient screwing
    • (Pre-)Drilling, thread forming and screwing in one work step due to drill tip and special thread geometry
  • No need for center-punching
    • Drill point allows precise positioning and ensures a precise drill diameter
  • Easy processing of wood to steel framing
    • The wings enlarge the hole in the wood, so that the threads of the screw can pass through the wood without binding, while the wings break off when hitting steel, allowing the threads to fully engage
