The fastening element which can be anchored by means of a hardening compound consists of a stay bolt (1), provided with a thread (1c), and a stay sleeve (2) connected thereto. The stay sleeve (2), consisting of an electrically insulating plastic, has circumferential ribs (2b) which are subdivided along the circumference into regions (2c, 2d) with an inclination directed towards different sides relative to the longitudinal axis of the sleeve. To achieve a good mixture and an even distribution of the hardening compound along the stay sleeve (2), the regions (2c) of the ribs (2b), inclined in the same direction relative to the thread (1c) of the stay bolt (1), have a greater radial extension relative to the other regions (2d). <IMAGE> |
