Reinforced sleeve expansion anchor is a mechanical anchor designed for medium to heavy-duty fastening in concrete and masonry. It features a threaded stud encased in a full-length reinforced sleeve and an expansion cone. Tightening the nut drives the cone, causing the sleeve to expand and lock securely against the hole wall, creating reliable holding power. It is engineered for structural attachment in environments without severe seismic demand.
