Huiyu Mechanical Expansion Anchor Bolt L130-380mm W10-30mm HY20210216B

‌Product Description

A Mechanical Expansion Anchor Bolt is a heavy-duty fastening device designed to secure structural elements to concrete, masonry, or similar solid substrates. It operates through a mechanical expansion mechanism: when tightened, the bolt’s wedge, cone, or sleeve component expands against the walls of a pre-drilled hole, creating a secure friction-based interlock. This design ensures high pull-out resistance and shear strength, even under dynamic loads or vibration. Made from corrosion-resistant materials such as galvanized steel, stainless steel, or zinc-plated carbon steel, these anchors are suitable for both indoor and outdoor applications. Installation requires no chemical adhesives, relying solely on mechanical force for immediate load-bearing capacity.
