The new anti drop fastener is compatible with a standard pipe diameter of 48.3mm, retaining the fast installation characteristics of traditional fasteners while achieving flexible conversion between right angle, rotation, and docking functions through modular design. The installation efficiency has increased by 40% compared to before the application of patented technology. In a chemical industrial park in Northeast China with low temperature and high humidity, the impact toughness of the product at -30 ℃ still reaches 95J. Combined with passivation and galvanizing dual rust prevention treatment, the corrosion rate is reduced by 90% compared to ordinary fasteners, and the service life is extended to 12 years.

   Relying on the pre assembly adaptability of BIM technology, this fastener achieves precise docking with an error of ≤ 0.1mm in prefabricated construction, reducing the scaffolding construction period by 15%. At present, it has been applied to 12 major projects such as the expansion of Shanghai International Convention and Exhibition Center, replacing more than 800000 sets of traditional fasteners and reducing the safety accident rate by 78%. It has become the core equipment for construction enterprises to implement the requirements of “Safety Production Month”.
