Strong connections. Purpose-built bolts and fasteners for wind power.

We have aligned our approach with the needs of the global wind power sector. Our technical team tailors the exact solution for your wind power project. Your components are manufactured to the highest standards in our state-of-the-art facility - orders can be fast tracked. And to keep your project's carbon footprint as low as possible, our production is powered with renewable energy. Products are rigorously tested and shipped using our global logistics network. And our smart chips and Vendor Managed Inventory service help simplify and optimize installation and maintenance.

The most automated production facilities. The closest partnerships. The widest logistical reach. All to deliver the strongest connection for your wind power facility.

Production powered by green energy

Our production facility in Norway is connected to the Norwegian power grid and operates using 98% renewable electricity. This is sourced from hydro-electric facilities. Given the energy intensive processes required to manufacture high quality, durable bolts, our use of renewable energy makes a significant contribution to lowering the total embodied carbon of your final product.

Materials tailored to project specs

Our advanced in-house heat treating process uses the latest in automation and robotic manufacturing, allowing us to harden materials to precisely the strength and quality your project demands.

Built for extreme conditions

Our experts are experienced at precisely calculating and analyzing the standards and specifications of your project in relation to the operational conditions your turbines will be under, including factors such as temperature, humidity and salinity. By understanding how these factors combine, we deliver the exact solution to handle even the most extreme conditions.

Installation and maintenance

Our fasteners are designed to be simple to install and maintain. For added data and intelligence - for example, batches, measured value and certification - you can select smart / intelligent bolts. A range of these bolts are available, including, for example, those with RFID chips integrated. We also provide pre-lubricated fasteners if required.

Meeting the highest industry standards

With the most-automated bolt production process in the world, our products meet the highest quality standards. Our wind turbine blade fasteners are ISO, DIN, and IEC certified.

Proactive partnership in customization

You bring the designs, we provide the expert advice and recommendations to find the best fit for your project. Our experienced team will help you to optimize your timeframe and budget by sharing their know-how on cutting edge fastener production.

Corrosion-resistant coating

A range of different coatings are available depending on your specific operational requirements. These include HDG, Zinc Flake, Sheradizing, Phosphate, Zinc Plate, and PTFE. We will advise you on which coating is the best fit for your project.
