FIELD: construction.
SUBSTANCE: bolt in its front end area has an expanding cone, designed to move an expanding sleeve radially apart when it is inserted into the expanding sleeve. The bolt has a threaded section for imparting the tensile force to the bolt. The bolt has a lip, that restricts the expanding sleeve shift away from the expanding cone, and wherein the bolt has at least one anti-rotation protuberance to prevent the rotation of the expanding sleeve relative to the bolt, that extends from the lip and protrudes radially outside from the bolt. It is provided, that axial length of the protuberance for turning protection is less, than the thread pitch at the bolt threaded section.
EFFECT: expanding anchor fixation reliability increase.
