BREA, C.A. – November 7, 2025 – Curtiss-Wright announced today that it has signed a new, exclusive teaming partner agreement with Tensor AB. Under the agreement, Curtiss-Wright will serve as Tensor AB’s sole channel to market and supply its Reactor Vessel Head (RVH) Tensioner, Bolt Gauge, Stud Runner, Multi-Stud Tensioners, and Single Stud Tensioners to the North American commercial nuclear market. Work under this agreement will be performed by Curtiss-Wright Nuclear.

“Collaboration within the industry is a critical strategy in supporting the global nuclear supply chain,” said Kurt Mitchell, Senior Vice President and General Manager, Curtiss-Wright Nuclear. “By combining our technical expertise with Tensor AB’s innovative bolting solutions, we have helped our customers improve efficiency, reliability, and performance in complex applications.”

Based in Gothenburg, Sweden, Tensor AB has been designing, producing, and servicing hydraulic tensioning systems since 1978.
