Corrosion resistant
Zinc plating holds up outdoors even in damp conditions.
Description
This high-strength inverted cone chemical anchor expansion screw is designed for securing heavy loads in concrete and masonry structures. Constructed from Grade 8.8 steel, the bolt features an inverted cone geometry that ensures uniform stress distribution and maximizes holding power within the base material. The expansion mechanism activates upon tightening to create a secure, vibration-resistant connection suitable for demanding industrial applications. Available in multiple metric diameters including M12, M16, M18, M20, M24, and M30, this specific unit corresponds to the selected size variant. Ensure the drilled hole is clean and free of dust before installation to achieve optimal bonding performance with the chemical resin.
