MKT Metall-Kunststoff-Technik GmbH & Co KG states its new BZ3 dynamic mechanical expansion anchor offers an efficient alternative to injection and undercutting systems in fatigue applications, as well as being one of the first mechanical expansion anchors with an ETA certification (ETA – 20/0117) for fatigue loading.

Available in sizes M10 to M16, the BZ3 dynamic is quick and easy to install and offers very shallow embedment depths, requiring only small concrete thicknesses to anchor into, with the product also capable of installation with small anchor spacings and edge distances.When using a hollow drill bit, no further cleaning of the borehole is required and the exposure of the installer to dust is reduced to a minimum. 

BZ3 dynamic can also be pre-set or conveniently installed through the attachment, with a red colour marking, making it easy to visually check the required anchorage depth. This anchor can be immediately loaded after torquing and is ready to withstand fatigue loads after the mortar, which is injected through the filling washer to close the annular gap between the attachment and the anchor, is hardened.

Also suitable for fastening light to medium fatigue loads in cracked and uncracked concrete, the BZ3 anchor is ‘Made in Germany’ under high social and environmental standards, making it a sustainably manufactured product for long-lasting and solid connections.

BZ3 dynamic is assessed according to the European Assessment Document (EAD) 330250, the qualification standard for anchors in fatigue applications. Its ETA certification also covers loading for seismic performance categories C1 and C2 and for fire exposure (R30 - R120).
