Element, in particular to be used in combination with sheet metal component, comprising rotation preventing projections integrated in inner surface

摘要

The element (10) is divided in an upper segment with a wider segment and a lower area (42) with a smaller diameter and is provided with an inner thread located inside the lower segment (42). The opening forming the inner surface of the upper segment is wider at the bottom and has a recess with a wider diameter below its flat upper edge (24). Several small projections (32) are integrated in the recess in order to prevent the element (10) from an unintentional rotation.
