Our field of activity covers all areas in which large, secure and, above all, releasable screw connections are required. We calculate, develop, design and produce the best technical and economical bolting solutions for large dimensions and high, precisely adjustable and releasable pretensioning forces in accordance with the specific requirements of our customers and on the basis of our high-quality mechanical Multi-Jackbolt Pretensioners (MJP).

For engineering tasks, we maintain a close and trusting cooperation with our customers. For the smoothest possible exchange, we therefore rely on the widely used 3D CAD development software SOLIDWORKS®.

Benefit from our many years of experience as a technology leader for highly stressed large-diameter bolted connections. We are happy to put our comprehensive know-how at your disposal and look forward to a successful cooperation.

If you have any questions, please do not hesitate to contact me.
