Hexagonal Expansion Anchor Bolts
— DISLAB Precision —
At DISLAB Precision, we supply high-quality galvanized hexagonal expansion anchor bolts, professionally engineered for concrete, masonry, stone and general construction fixing projects. These heavy-duty expansion anchors deliver stable gripping force, reliable installation and long-term safety under static and dynamic loads.
Made from premium carbon steel with hot-dip galvanized finish, these expansion anchors provide excellent rust and corrosion resistance, suitable for indoor, outdoor, coastal and humid working environments. The standard hexagonal flange design ensures easy tightening with common tools, while the integrated expansion sleeve creates strong wall gripping after installation. We offer a complete size range from M6 to M16, covering multiple lengths and matching drill hole specifications to fit various construction and installation demands.
