Wind energy is one of the fastest growing and renewable energy technologies. Global installed wind generation capacity onshore and offshore has increased almost 80-fold in the last twenty-five years.

 Many parts of the world have strong wind speeds. Due to the low pressure effect, the wind blows faster at higher elevations. The increase in speed at altitude is more effective near the surface. The terrain is affected by surface roughness and wind obstructions such as trees and structures.

Intenfa produces world-class 10.9 and 300 HV quality bolts, nuts, washers for use in wind energy. These bolts, nuts, washers are produced in uncoated, black and hot-dip galvanized in accordance with European and American standards. Where appropriate, we can also supply these bolts, nuts, washers in special coatings such as PTFE, Geomet and Dacromet coating.

These HV bolts comply with 10.9 quality and are supplied with Grade 10 nuts and washers suitable for 300 HV used in wind turbines.

If desired, we can produce bolts, nuts, washers for wind turbines, with dimensions starting from M16 and up to M200.
