Abstract
(DE)
Die vorliegende Erfindung betrifft eine Schraube (10) mit einem Schaft (12), der einen gewindebehafteten Schaftabschnitt (13) und einen gewindefreien Schaftabschnitt (14) aufweist, und einem Kopf (15), der eine im Wesentlichen plane Anlagefläche (16) zum Anlegen an ein Bauteil (31) aufweist, wobei der Mittenrauwert einer Oberfläche der Schraube (10) einen Wert von höchstens 0,04 μιη aufweist. Die vorliegende Erfindung betrifft ferner ein Verbindungssystem (40) mit einer solchen Schraube (10) und ein Verfahren zur Oberflächenbehandlung geeignet für eine solche Schraube (10).
(EN)
The present invention relates to a screw (10) comprising a shaft (12), which has a threaded shaft section (13) and a non-threaded shaft section (14), and a head (15), which has a substantially planar contact face (16) to be applied against a component (31), wherein the average roughness value of a surface of the screw (10) has a value of a maximum of 0.04 μιη. The present invention further relates to a connecting system (40) comprising such a screw (10) and a method for surface treatment suitable for such a screw (10).
(FR)
L'invention concerne une vis (10) comprenant une tige (12) qui comporte une partie de tige (13) munie d'un filetage et une partie de tige (14) dépourvue de filetage, et une tête (15) qui comporte une surface d'appui sensiblement plane (16) pour l'appui contre une pièce (31), la rugosité moyenne d'une surface de la vis (10) ne dépassant pas une valeur de 0,04 μm. La présente invention concerne par ailleurs un système de raccordement (40) comprenant une telle vis (10) et un procédé de traitement de surface destiné à une telle vis (10).
