The high-performance concrete screw for absolute installation ease. * The first concrete screw with diameter 6 and variable embedment depths enables high flexibility and a precise adaption on the loads. * The ETA assessment option 1 includes the use in cracked and non-cracked concrete for highest safety requirements. * The first 6 mm diameter concrete screw with an ETA assessment for the C1 seismic performance category for additional safety standards. * Fischer concrete screw UltraCut FBS II 6 SK is made of zinc-plated steel with a countersunk head. * The UltraCut FBS II 6 SK is perfectly designed for applications like fixings of pipe routes, channel systems, ventilation ducts and facilities in the building service engineering. * When the concrete screw is screwed into the drill hole using an impact driver, the thread flanks cut deep into the concrete, thus ensuring top load-bearing capacity. * The low drilling effort saves time in the case of multiple fixations. * The European Technical Approval for cracked concrete and non-cracked concrete as well as for seismic loads and classification into fire resistance class R 120 guarantee even more safety.
