The Fischer FSU-P undercut anchor is a self-tapping undercut anchor made of stainless steel for applications that require the highest loads and safety, such as in heavy steel construction, nuclear power plants, and the oil and gas industry. The undercut anchor is ideally suited for heavy-duty fastening to secure steel structures, heavy pipelines, and industrial machinery in outdoor settings in cracked and uncracked concrete. The FSU-P is installed using the FSU-ST setting tool into a drilled hole created with the FSU-SD core drill. The anchor self-cuts the undercut, creating a form-fitting connection. This ensures maximum safety, even with large crack widths in seismic areas. The anchor can be quickly and residue-free removed with the FSU-DT removal tool.
