China's high-end fasteners rely on imports, old engineers invent new models, or will break the foreign monopoly!

[Abstract]:
China's high-end fasteners rely on imports, old engineers invent new models, or will break the foreign monopoly! Although Chinese ancients have excellent mortise and tenon design, but in today's dense steel building, the importance of threaded connection in the current building is self-evident. Nowadays, even if people invented good bolts and nuts, in many large-scale projects or high-speed and strong equipment operation, various disasters caused by loose connections between bolts and nuts continue to emerge.
