Akbarali Enterprises is a leading blade stud bolts manufacturer, specializing in high-tensile double-end stud bolts for wind turbine blade and hub assembling. These bolts are usually made from carbon steel grades 8.8, 10.9, and 12.9 as per ISO 898-1:1999, ensuring that these bolts have very high strength and are fatigue-resistant. Each blade stud bolt has rolled threads-stud threads are rolled after heat treatment-because rolled threads can increase torque capacity and fatigue performance by more than 50%; stud diameter ranges from M20 to M64.
Being B2B-oriented, these blade stud bolts are supplied in bulk to wind energy OEMs, turbine manufacturers, industrial fabricators, and machinery builders. They are available in standard and custom sizes with optional low-friction (0.02 CoF) and corrosion-resistant coatings such as Xylan, zinc plating, and hot-dip galvanizing. Designed to perform in extreme temperatures from -250 °C to +285 °C, these bolts offer excellent wear resistance, long service life, full material traceability, and optional immaterial testing to meet stringent industry standards. Connect with your trusted supplier today to discuss your requirements and get the best price on bulk orders.
These have equal length threads on both ends and are used to fasten turbine blades to the hub via cross nuts. They’re typically made from carbon steel grades (such as 8.8, 10.9, or 12.9) and manufactured to ISO 898‑1 standards
These bolts include low‑friction coatings like Xylan, PTFE, or zinc‑flake and can handle wide temperature ranges (–250 °C to +285 °C). They offer enhanced corrosion resistance, fatigue strength, and wear resistance—ideal for demanding offshore and onshore wind turbine environments
What are blade stud bolts?
Blade stud bolts are double-ended threaded rods used to securely anchor wind turbine blades to the hub . They are nuts-free bolts—threaded on both ends—to ensure a solid blade-to-hub connection. Typically made from high-strength carbon steel and graded per ISO standards, they offer excellent fatigue resistance and are coated.
Where are they used?
Blade stud bolts are primarily used to securely fasten wind turbine blades to their hub assemblies. They enable safe and stable blade-to-hub connections in both onshore and offshore wind energy systems, meeting high strength and fatigue demands .
How are they designed?
Blade stud bolts are meticulously engineered double-ended threaded rods specially designed for wind turbine blade-to-hub assembly. They conform to ISO 898‑1 standards, ensuring precise dimensions and mechanical properties. The threads are rolled after heat treatment to induce compressive stresses at the roots—boosting fatigue resistance by more than 50% and providing a smooth thread surface.
