The Fischer high-performance anchor FH II S with hexagonal head is a sleeve anchor made of galvanized steel. The anchor is installed using a time-saving through-hole mounting method. When tightening the anchor, the cone is pulled into the expansion sleeve, which then presses against the wall of the drilled hole. The black plastic ring prevents the anchor from rotating and absorbs the tightening slip. This pulls the attachment component against the anchoring substrate. The Fischer high-performance anchor FH II S with hexagonal head is ideally suited for securing brackets, steel constructions, and cable trays in cracked and uncracked concrete.
