Product Description

The fischer ZYKON Hammerset anchor FZEA II is an internal threaded anchor made of zinc-plated steel. The special drill bit FZUB is used to create the undercut drill hole in a single work step. The undercut anchor is set in the time-saving through-type installation. The expansion sleeves are driven in with the setting tool FZED Plus by driving in the internal expansion pin above the cone. This fills the undercut drill hole with a positive fit. The fischer ZYKON Hammerset anchor FZEA II is suitable for single-point fixings of pipelines, suspended ceilings, and sprinkler systems within internal areas in cracked concrete.
  • Hammerset anchor with Zykon undercut technology for individual fixings in cracked and non-cracked concrete.
  • The combination of hammerset and ZYKON undercut anchor allows for individual fixings in cracked concrete.
  • The special ZYKON undercut technology reduces the energy required for installation.
  • The FZUB special drill allows for a fast installation by creating the undercut without having to change tools.
  • The embossing that is applied when expanding the anchor secures the simple control of the anchoring.
  • The almost expansion-free installation of the anchor allows small edge distances and axial spacing, thereby enabling flexible use.
