From clamping systems to tensioners: Berardi Group solutions for the industry

With over a century of experience in industrial distribution, Berardi Group specializes in supplying fastening elements, industrial components, and personal protective equipment. The company ensures tailored solutions, wide product availability, and fast deliveries.

Among its strategic partners, Berardi Group distributes the advanced solutions of Nord-Lock, a Swedish company that has been specializing in fastening systems for bolted joints exposed to vibrations and dynamic loads since 1982. Below, we present the main products offered for industrial fastening.

Nord-Lock washers: secure fastening

Nord-Lock washers utilize tension rather than friction to lock bolted joints. The system, consisting of a pair of washers with cams on one side and radial teeth on the other, ensures a secure and durable fastening, reducing the risk of loosening. They are available in carbon steel and stainless steel in various sizes, ranging from M3 to M130.

Wheel nuts: enhanced safety for heavy vehicles

In heavy vehicles, preload loss can cause movement between joint components and rotation of the wheel nut, compromising safety. Nord-Lock solutions, made of hardened steel with an anti-corrosion coating, prevent this issue, ensuring a stable and reliable assembly.

Superbolt tensioners: precise tightening with minimal effort

Superbolt tensioners, made of high-strength steel, replace traditional nuts and bolts, allowing for precise tightening of bolts, studs, and threaded rods without excessive manual effort. They are available in a wide range of sizes, from M16 to M160, and can handle preload forces up to several thousand kN.

Boltight hydraulic tensioning: speed and efficiency

For more than a decade, Boltight has been a benchmark in hydraulic bolt tensioning. Its high-strength steel tools with anti-corrosion coating ensure precise, safe, and simultaneous tightening of multiple bolts, optimizing maintenance time. They are compatible with bolts ranging from M16 to M400 and operate at pressures up to 1,500 bar.

Expander System: the solution to pin wear

Pin wear is one of the major causes of failure in industrial equipment. The Expander System eliminates this problem without the need for welding or reaming, improving reliability and reducing maintenance costs.

Thanks to strategic partnerships with major brands like Nord-Lock, Berardi Group provides innovative and reliable fastening solutions for the industry, ensuring high quality, safety, and performance. For more information, contact the company using the provided details.
