about auxano technologies - suppliers of hydraulic bolts



All ship yards strive to meet and exceed the expectations of their clients. However this must be achieved within budget. At Auxano, we recognise that commercial requirement. The Easi‐Fit and the Flexi‐bolt provides a high quality product that is appreciated by Owners yet commercially viable for ship yards.

When considering which type of bolt to use for connecting sections of the propulsion shaft, it is often assumed that the costs of hydraulic bolts are too high to justify their inclusion.

When specified by the client, the cost can often be surprisingly high. At Auxano we have introduced high quality materials, experience, design and specification, with a dedicated and global after sales support service, but at a price acceptable to the yard..
