Since 1979: Friction and torsion free pre tensioning as a foundation

ITH stands for Industrial Technical design Hohmann ("Industrie-Technische Konstruktionen Hohmann"). This was the name given to the company by Hans Hohmann when he founded it in 1979 in Meschede, Germany. Meschede is still the headquarter but ITH has more than 40 global representations worldwide. 

The first product marketed by the new company was a bolt-tensioning cylinder (BTC) working on this principle: the ITH Stretch Method (hydraulic, friction- free and torsion-free tensioning of bolts by hydraulic stretching of the bolt). With its high-accuracy (± 2,5 %), the bolt-tensioning cylinder is still one of the most accurate tools on the market for tightening large fasteners.
