Turbine Bolt

Astec Tube is a leading Turbine Bolts and Nuts Manufacturer offering a wide range of high performance fasteners for critical applications. We manufacture turbine bolts with high performance in extreme and harsh conditions in steam, gas and wind turbines.

What is a turbine bolt?

Turbine bolts are fasteners made specifically to join together major turbine components such as flanges, casings and rotors when exposed to vibration, stress and temperature. Our turbine bolts are used in power generation industries where safety and sustainability are paramount.

We supply turbine bolts with diameters from 1/4” to 2” and M6 to M52 (metric sizes). Our range of turbine bolts are available in grades including 718, 660 class A/B/C/D, SS321, SS410, B4B, B8M class 2, B7 and B16 that meet the load required and the varying temperature tolerances. Turbine bolts provide high tensile strength, corrosion resistance and thermal stability. Our fasteners are available in special coatings such as silver plating and electroless nickel for extra protection in harsh turbine environments.

Turbine bolts such as wind turbine bolts, gas turbine bolts, steam turbine fasteners and turbine coupling bolts are available to meet a variety of application needs. We also manufacture wind blade bolts, turbine flange bolts, turbine holding down bolts and turbine casing bolts. These fasteners provide excellent fatigue strength, ease of installation and strict diameter and length control. Our fasteners for wind turbines are manufactured with weather-proof coatings, high-quality materials to perform in extreme wind conditions.

Which bolts are suitable for wind turbines?

We have the right steam turbine coupling bolts, wind turbine anchor bolts and fasteners to manage high winds, vibrations in service and outdoor exposure. Our fasteners are used at power plants, energy farms and industrial turbines for securing turbine flanges, joining turbine casings, anchoring turbine blades or coupling shafts on steam or gas turbines. These bolts are essential for power generation and structural integrity.

Our turbine bolts are produced in accordance with strict quality specifications. We comply with international standards such as DIN 2510 part 2 and DIN 13. Each product is inspected for its material, dimensions and coatings. We are certified with AD 2000 Merkblatt, EN 10204-3.1/3.2, EN 10269 and PED 2014/68EC to meet international regulations.
