Our stainless steel fasteners are used by customers in various energy-related applications around the world.

Energy fastener applications

  • Oil and gas
  • Power generation
  • Nuclear
  • Renewable energy
  • Battery systems
  • Transmission and distribution

Our energy sector offering

BUMAX stainless steel fasteners are used in critical offshore wind turbines, tower and “jacket” support structures, and wave power plants due to their corrosion resistance, high strength and excellent fatigue properties. Customers choose our products due to their reliability and low requirements in terms of maintenance, replacement and lifecycle costs.

Similarly, our products are used to secure critical components in fusion and nuclear reactors. Such applications may require high temperature resistance and materials low in undesirable elements such as cobalt.

We offer a broad range of products and can deliver customized stainless steel fasteners according to unique customer requirements. Our fasteners are delivered with full traceability and 3.1 or 3.2 certificates on demand. We can offer fasteners with a Premarket Approval (PMA) for Pressure Equipment Directive (PED) applications  in accordance with PED 2014/68/EU.
