As a system supplier, ITH produces high-quality connecting elements in addition to its high-precision tools for tightening and loosening large bolts.
The threads of the bolts are manufactured using the high-precision cold-rolling process. The high standard of quality and our own mechanical production facilities allow us to produce special bolts in various sizes with close tolerances. The range begins with M20 (3/4").
The production process is subject to continuous quality control. Depending on the customer's requirements, it is possible to have safety-critical connecting elements acceptance tested by the following organisations in ITH's plant:
American Bureau of Shipping (ABS)
German Lloyd (GL)
Büro Veritas (BV)
Technischer Überwachungsverein (TÜV)
