ITH Bolting Technology company portrait

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.

ITH is a family owned business in its second generation. Both sons Frank and Jörg Hohmann have built the tool making company into today's system supplier with a worldwide reputation. ITH operates 12 own technical sales and service subsidiaries in:

• Spain, France, United Kingdom, Japan, China, Malaysia, India, Australia, United Arab Emirates, South Africa, Brazil and USA.

ITH guarantees proximity to the customer and fast service worldwide with more than 40 global locations in total.

ITH Customer Focus stands for:
All company activities are one hundred percent geared to the customer's requirements and the quality management guidelines according to DIN SO 9001. All production steps in the production processes from testing the raw material until the testing of the end product are carried out at the headquarters in Meschede (Germany). Therefore we have complete documentation and control of the whole production process.

ITH business partners - many market and industry leaders are using the quality and technical know-how of ITH.

A high percentage of ITH bolting tools and solutions are designed to customer's specifications. Spare parts need to be available quickly worldwide which is guaranteed by:

• A unique in-house production rate of more than 90% enables ITH to react quickly to demands for new tools and spare parts.
• All bolting tools and hydraulic pumps are developed and produced by ITH which leads to fast delivery of spare parts.
• ITH operates a worldwide network of subsidiaries with high stock capacities in the local markets.
  

One of a kind ability to innovate: More than 200 nationally and internationally registered patents show our technical competence. Many of the ITH developed solutions are today an industry standard. The knowledge of more than 40 years is incorporated in the continuous innovation of new products.

We are still driven by the desire to innovate and we are developing the best technical solution that economically fits the customer's needs.
