The sleeve anchor fixing consists of a cylindrical metal sleeve with internal threads, a nut, and a screw or bolt. The sleeve is inserted into a pre-drilled hole in the masonry surface, and the nut and screw are then tightened to expand the sleeve and create a tight grip on the surrounding material. This creates a strong and secure connection that can support heavy loads and withstand the test of time.
