The Φ80-89 expansion anchor 8x70, also known as an ordinary expansion bolt 8x70 or 8x70 mechanical anchor Φ80-89, is a heavy-duty fastening solution designed for robust anchoring in concrete, masonry, or solid substrates. With a nominal diameter range of Φ80-89 mm and a length of 70 mm, it provides high tensile and shear load capacity, ideal for structural applications in construction, industrial installations, and infrastructure projects. This anchor requires a pre-drilled hole matching its diameter for optimal expansion and grip. Operating within standard environmental conditions (-20°C to +60°C), it features corrosion-resistant materials for durability. Key advantages include rapid installation, reliable load distribution, and suitability for static loads, though precise hole alignment is critical. Limitations include incompatibility with hollow or brittle materials and dynamic load scenarios.
