FAQ about TENZ Screws

TENZ® is  ascrew for wood! It makes drilling in the screw easier and saves energy. Working with TENZ® is simply fun.

Numerous awards testify to the innovative power of the screw and the company. Here, too, we are rethinking the screw.

TENZ® is a new award-winning thread technology with an energy-saving effect. TENZ is the Austrian State Award winner 2017 & 2019. The jury justified its decision with the successful challenge of “reinventing” such an established technology as the screw.

“Ingeniously simple – simply ingenious: the low-energy screw ‘Made in Austria’ has shown that it is possible to create a world-leading innovation even in a seemingly simple technology, to open up new markets and to make a contribution to the environment and occupational safety in the process,” said the State Prize jury.

Less friction = Easier screwing = More fun at work! Frictional forces always act in a way that opposes motion, slowing it down or preventing it altogether. A key factor in the occurrence of frictional forces is surface texture. The geometry of the TENZ® screw makes it possible to minimize friction.

The secret behind TENZ® screws lies in the steps positioned along the thread. These gently displace the wood fibers. The interaction of the pairs of steps is what makes TENZ® Stairs thread technology unique.

TENZ® is suitable for any wood joint and, requiring less effort, is the best choice for industry, trades, and home use—versatile, easy, and safe to use.

The unique selling point is that the wood fibers are compressed and pushed together rather than milled or drilled. This results in lower energy consumption during the screw-fastening process. This is achieved by a quasi-oval cross-section in the area of the thread.

The desire to combine energy savings during screw-in with easier handling was the driving factor. Much of what exists in our world can be derived from nature.

The unique thread shape of the TENZ® screw is modeled after the inherent shape of a DNA double helix. This shape was experimentally adapted to the screw over a period of three years until the perfect geometry was finally achieved: TENZ STAIRS THREAD TECHNOLOGY®—minimal resistance to screw-in with optimal technical performance and maximum efficiency when screwing.

Gerhard Hubmann, the inventor of TENZ STAIRS THREAD TECHNOLOGY®, lives and breathes screws. A native of Austria who resides primarily in Styria, he has over 25 years of experience in fastening technology, with a focus on screws. He has introduced successful innovations to the screw market for many well-known companies in Europe. As a professional in the field of screw manufacturing and application, he possesses considerable expertise regarding the requirements for the “perfect screw.” As a driving force for innovation in the field of screw technology, he is delighted with the global marketing and success of the TENZ® wood screw.

The effectiveness of the screw has been scientifically studied and proven. Studies by KIT—the Karlsruhe Institute of Technology*—show that the offset core diameter of the screw significantly reduces the required tightening torque

*Karlsruhe Institute of Technology – The University of Karlsruhe, led by Prof. Dr.-Ing. Hans Joachim Blaß, director of the Institute for Timber Construction and Building Structures, is the most internationally renowned research unit for connection technology in timber construction.
