Information about screws

A screw is a bolt with a thread. Screws are used for a removable connection between components of all types. The threads are turned into an internal thread, in which the connected parts are compressed. The screw holds the parts by a clamp connection together, it is only drawn on tension.

Graewe Tadiv, based in the South-East of Europe in Bosnia, has been producing screws and cold forming parts for more than 20 years for Graewe. As a result of the long and successful business relationship, Graewe decided to intensify the relationship. After the change of name in the year 2006, this company is now under the management of the family Graewe and produces exclusively for GRAEWE in Germany.
