The fischer heavy-duty anchor TA M is an internal threaded anchor made from zinc-plated steel for pre-positioned installation. The heavy-duty anchor is ideal for anchoring fall protection devices, systems, and machines in non-cracked concrete. The optimised anchor geometry minimises setting energy and allows for use in really confined spaces. During the installation, the cone is pulled into the expansion sleeve and expands it against the drill hole wall. The three-part expansion sleeve creates even load distribution, thus allowing small edge and axial clearances. The plastic cap protects the thread from soiling. This keeps the thread smooth.
