Abstract
The anchor bolt comprises a generally hollow body (1) with a drilling end (4), a supporting collar (5) at the other end and an external screw thread (6). The collar (5) forms two openings (10, 11), diametrically opposed, for receiving an anti-rotation pin (8, 9) removably fixed to the collar (5) and movable in the opening (10, 11). The pins (8, 9) are intended to anchor both in the collar (5) and in the receiving material, in order to prevent rotation of the bolt.
