<p>A flanged sleeve (24) is screwed into the internal thread (20) of expansion sleeve (12) which is introduced into a bore (26) formed in the anchor base (11) in such a way that the sleeve is placed with the lower face of flange (28) on the base or the upper edge of bore. A drive-in bolt (32) is driven in the setting direction (16) in such a way that the expansion structure (22) is pressed deeper into the sleeve. The expansion tongues (18) are expanded for anchoring in the base. The sleeves are connected together using the drive-in bolt. An independent claim is included for system for setting self-cutting undercut anchor into anchor base.</p> |
