Tenz Low energy screw
Some see a screw - we see new possibilities

Reinventing the screw

There are people who have a different view of the world. Gerhard Hubmann, the managing director of TENZ and inventor of the new wood building screw, is one of them. He has been working with screws for wood construction for over 20 years.

From his expertise in all aspects of this everyday product came his drive to reinvent the screw. Two central problems for the application of a screw in wood were particularly close to his heart:

  • Reduce the use of force during application
  • and minimise the energy required.

The Idea

Gerhard Hubmann says: "I thought of one of the original forms: a double helix. I simply divided the helix and moved the segments towards each other. Because the special shape means that only one part of the screw ever comes into contact with the surrounding wood, I achieve a significantly reduced friction and thus reduce the amount of force needed to screw it in."

Production readiness & foundation TENZ

After 3 years of development work in cooperation with the University of Karlsruhe (KIT) and the Technical University of Graz, the TENZ Stairs Thread Technology is ready. The idea became a finished product and is now ready to conquer the world. The focus of the far-thought technology is on the environment and people, and a system from which both benefit.


Staatspreis 1

Austrian State Prize for Engineering Consulting 2017

The State Prize Consulting - Engineering Consulting of the Austrian Ministry of Economics goes to the project "TENZ - The low-energy screw for wood / Die Profi-Holzbauschraube mit der innovativen Stairs Gewindetechnologie".

The jury justified its decision with the successful challenge of "reinventing" such an established technology as the screw: „Genial einfach – einfach genial: die Niedrigenergieschraube ‚Developed in Austria‘ hat gezeigt, dass es möglich ist, selbst in einer scheinbar einfachen Technologie eine weltweit führende Innovation zu schaffen, neue Märkte zu erschließen und dabei auch einen Beitrag zur Umwelt und Arbeitssicherheit zu leisten“, so die Staatspreis-Jury.

Red dot award : packaging design 2018

The sophisticated packaging design of the PEEKBOX was awarded the Red Dot Award: Packaging Design 2018.

The screw head serves as a button to open the presentation box, which arouses the consumer's curiosity. The hinged lid inside allows a first glimpse, as if through a circular keyhole, of the screw's most significant innovation - the TENZ® Stairs. The screw can be turned on its own axis in the special folding box and playfully shows how it works. Developed with the packaging specialist A&R Carton from Graz & the renowned design agency moodley brand identity .
