Wedge Anchor BZ plus



Due to its high performance as well as its easy and quick installation, the wedge anchor BZ plus with European Technical Assessment can be used for a wide variety of applications. The long thread length and two approved anchoring depths allow the BZ plus wedge anchor greater flexibility of use. The option for reduced anchoring depth saves time during drilling and reduces the installation effort. Using a suction drill also eliminates the need for blowing out the drilled hole.

The wedge anchors BZ plus M8 - M20 are also approved for use under seismic loading C1 and C2 up to an anchor length of 210 mm1). By using the new VS filling washer, the permissible seismic loads can be increased even further.

The sherardized wedge anchor BZ plus sh version with a zinc thickness of more than 40 μm offers increased corrosion protection compared to zinc electroplating.

For timber construction, the BZ-UH-plus version is available packaged with the washer DIN EN ISO 7094 (DIN 440).
