Beschreibung
Zusammenfassung:	The self-tapping screw (1) is made of a low-strength non-ferrous material, and comprises a screw body (3), which is provided with a coating (5) in areas. The coating is formed from an elastomer or polymer material enriched with fillers. The screw body has a trilobular cross-section. The screw material is aluminum, magnesium or their alloy. The coating is formed from a nanocomposite material, such as an acrylate or silicate composite material, and has a lower hardness than the screw material.
