Both tower bolts and wind power anchor bolts are used for new energy wind power generation. The tower bolts are made of high-strength steel and are mainly used as high-strength bolts for connection between towers. The service environment of tower bolts is harsh, and they must pass the test of severe winter and heat. The stress environment they bear is relatively complex, which is a dynamic and changeable environment.

The tower of wind power generation mainly plays a supporting role. Since the tower of wind turbine is usually high, up to 150 meters high, it requires multiple sections to be separated and connected through fasteners. The tower bolts used for connection need high strength to ensure the normal operation of the whole wind turbine.

Common specifications of tower bolt: M36, M42, M48, M56, length: 195mm -- 340mm, grade: 10.9, material: 42CrMo, executive standard: GB/T5782; Surface treatment: Dacromet, zinc aluminum composite coating and hot galvanizing coating.
