FIELD: construction.
SUBSTANCE: invention relates to a fastening element, in particular a spacer anchor. Fastening element comprises bolt (10) and fixing element located on bolt, for creation of tensile forces in bolt. Bolt has first metal friction surface (19), and the fixing element has the second metal friction surface (29, 79) connected to the first friction surface. Coating (60), which includes particles (61), preferably solid particles, is located on at least one of said two friction surfaces.
EFFECT: higher efficiency and reliability of the fastening element, ease of manufacture.
