The undercut anchor with an internal thread for M8 threaded screws for natural stone or artificial concrete panels

Zykon-Panel anchor FZP II M8i

The undercut anchor with internal thread for a concealed flush or stand-off installation of heavy façade panels out of natural stone. Calibrated panels or reveal panels can be flush mounted and panel tolerances can be adjusted through the stand-off installation. Due to the internal thread, there is no protruding external thread. Thus panels can be prefabricated and transported in a space-saving manner. This improves the economic efficiency and flexibility of the system.

The advantages / Product description

Advantages
  • The flush-mounted anchor allows for easy, economical construction of reveals.
  • Depending on the application, the user can choose between flush installation with an absolute anchoring depth, for instance for reveal panels, and stand-off installation technology with a constant remaining wall thickness that serves as a reference dimension to compensate panel thickness tolerances.
  • There is no protruding external thread, allowing a space-saving transportation of pre-fabricated façade panels.
  • The matching shape of the undercut anchor creates a inter-locking and stress-free fixing in the conical undercuted drill hole.
  • The fixing is not externally visible, creating a visually appealing façade surface.
  • Setting the anchor using undercut technology allows the user to select the best structural position in the façade panel. This significantly reduces the bending moment of the panel.
  • The anchor allows higher failure loads compared to common systems.

Application and approval

Applications
  • Exterior façades
  • Interior façades
  • Façade reveals
Building materials
  • Natural stone (>20mm)
You can find detailed information on building materials in the registration document.
Approvals

Assembly instruction

Functionality
  • The hole is either drilled to a constant reference dimension for the remaining wall thickness (RWT) or with an absolute anchoring depth.
  • The anchor can be installed flush or stand-off.
  • The compensation of panel thickness tolerances results in a completely flat façade surface.
  • Wet diamond drilling: first cylindrical, then conical - to create the undercut. #Inserting the undercut anchor in the cylindrical-conical undercut hole
  • Expanding the undercut anchor by "pressing down" the washer using the setting tools
  • Stress-free and geometrical inter-locking fixing
