<p>The anchor bolt is for insertion into a bore, and has a channel with an opening, for application of an adhesive. After hardening, the adhesive connects the bore wall and the bolt, which has one or more sealing rings to limit the length of adhesion. The bolt surface (1) has a projection to influence the adhesive which flows between the bolt and the bore hole wall (3). The projection may consist of a helical web, extending opposite to a thread of the bolt outside the bore, and which forms the channel. The bolt may have an additional channel, which extends over only part of its length. The channel aperture may be sealed by a sealing ring.</p> |
