<p>The invention relates to a method of producing an expansible anchor having, at its front end, a cone (5), provided with a low-friction coating, for expansion of a slit expansion sleeve (6) and having, on its rear end, a thread (2) for fastening an article to a building component. In order to improve adhesion of the low-friction layer to the cone (5) and to prevent damage to the low-friction layer during expansion, the surface of the cone (5) is so treated with steel brushes before the low-friction coating is applied that a score structure (11) is produced.</p> |
