fischer’s new FAZ II bolt anchor has been designed for safe anchorage of wooden structures in concrete. High shear and tensile load bearing capacities and variable anchorage depths offer a wide range of applications.
Wood is becoming an increasingly popular building material in construction due to its carbon neutrality and material properties. To fulfil this growing trend, fischer GmbH provides a range of bolt anchors within its FAZ II family.
A new ETA assessment of the range has now increased the shear and tensile load capacities of sizes M8 – M12 in cracked concrete, allowing fixings to be completed with fewer anchoring points. The additional ICC approval enables its simple application in buildings in the USA and countries in the Far East. The FAZ II can also be used at a low anchorage depth and requires little drilling.
The revised ETA assessment also allows for variable anchoring depth of the plugs in sizes M8 – M16, allowing for various solutions according to the respective load requirement or the existing component thickness. This allows for fixings to be implemented with shorter plugs, a smaller drilling depth and thinner concrete components, saving both time and money. The ETA also regulates the same loads as hammer drilling for diamond set holes from size M8 onwards. 
Various versions of the fischer bolt anchor, such as the FAZ II GS, allow applications which combine steel fixtures with slots or with tension anchors.
The FAZ II HBS, made of zinc plated steel, enables flexible and simple installation. The extra large washer conforms to the DIN 1052 wood construction standard and improves the load transfer between bolt anchors and joists or beams.
fischer also offers a bolt anchor with a diameter of 6mm and an ETA option 1 for cracked concrete with its FAZ II M6. It can be used to attach fixture thicknesses of up to 20mm. Its small diameter and short anchoring depth of 40mm save the user time, cost and effort while anchoring fixtures in concrete.
The FAZ II H bolt anchor with a cup nut possesses a rounded head shape which prevents injury and improves the appearance of visible fixings for elements such as indoor wooden staircases.
