Unit to be used as pre-assembled fastening module, comprising screw, sleeve, and ring serving as sleeve holding element

摘要

A pre-assembled module, comprising a screw (1) with a shaft accommodated inside a sleeve (2) is normally joined by welding, gluing, or a deformation of the sleeve (2). Some of those methods are time consuming, others can cause corrosion leading to a premature wear and tear. The shaft of the screw (1) of the new design of a fastening module is accommodated inside a sleeve (2) and held in position by a ring-shaped element (3) pressed into the sleeve (2).
