Expandable anchor bush for masonry - has screw bush with eccentric clamp ring to tighten as rotated

摘要

The anchor plug is for installation in masonry (18). It has a separate screw bush (9) with an external eccentric sleeve (5). The bush is installed in the blind location hole by rotating it relative to the eccentric clamping sleeve (5) by a screw driver. The expandable anchor tube (2) is located over the tapered end on the screw bush (9). As the anchor bolt is installed in the screw bush, the resulting axial compression of the anchor tube produces the required radial expansion.
