Wind Turbine Anchor Bolt Types

Wind turbines use high-strength bolts and nuts with many varieties and special materials, and the special working conditions of fasteners must have good mechanical properties. At present, there are roughly three types of fasteners used in domestic wind turbine projects:

Wind Foundation Anchor Bolt

High Strength Anchor Bolt is applied to wind turbine foundation system and wind tower structure. Characteristics: excellent anti-delay fracture performance and long fatigue life.(Fatigue Test: not damaged after 12 million test). The first step of wind power project is the foundation work, anchor bolt provide support and resistance to the tower and also forms a solid foundation to the whole structure, high strength anchor bolt is the fastener between wind turbine and concrete anchor cage structure.

Wind Turbine Foundation Bolt

Quenching plus tempering or other surface treatments at different temperatures will impart different performance properties to the fastener. Under certain conditions, the quality of raw materials will affect the selection of heat treatment process parameters, and directly affect the comprehensive mechanical properties and safety of high-strength fasteners for wind power. If your project need high quality anchor bolt, you can contact us now for price and details.

Tower Bolt

It is the bolt used on the tower of wind turbine. It mainly uses GB/T 1228~1231 DIN6914~6916 and large hexagonal steel structure connecting bolts such as DAST.

Wind Turbine Anchor Bolts

Bolts used on wind turbines, mainly includes: hexagonal head bolts, hexagon socket bolts, hexagons nuts and washers such as GB/T 5782, GB/T 5783, GB/T 70.1, GB/T 6170, GB/T 97, etc.

Blade Bolts

Bolts that connect wind turbine blades, mainly non-standard stud bolts and T-shaped round nuts for some products.

Bolts and screws are 10.9, a few are 8.8; nuts are 10, 8; the hardness of the gasket is 35-45HRC, these varieties must be quenched and tempered to achieve the specified mechanical properties.
