Concrete screw BSZ A4 Stainless steel A4 Concrete screw BSZSU A4 Concrete screw BSZSK A4 Concrete screw BSZK A4 Concrete screw BSZB A4 Approvals and Certificates Range of loading: 0,4 kn 19,4 kn

1 Concrete screw BSZ A4 Stainless steel A4 Concrete screw BSZSU A4 Concrete screw BSZSK A4 Concrete screw BSZK A4 Concrete screw BSZB A4 Approvals and Certificates Range of loading: 0,4 kn 19,4 kn Range of concrete quality: C/2 C/60 Ø6 Option 1 proved concrete screw BSZs cut a positive thread in the concrete when being screwed in and enable attachment to be made close to the edge through the expansionfree operating principle (=undercut). The proved adjustment enables subsequent alignment to compensate for unevenness. The BSZ A4 concrete screw is also ideal for temporary fixings since it is fully removable. Installation with an impact screwdriver means that you do not need to use a torque wrench. It is quick, reliable and reduces assembly errors. Ø8Ø R0R1 Applications To anchor moderate to heavy loads outside and inside in cracked and noncracked concrete: Railings and handrails, steel beans, wooden beams, supports and braces, brackets, pipeline and cable routes, suspended ceilings, etc. The BSZ A4 concrete screws are available with connection thread and with a range of different head shes for a wide variety of plications. Advantages European Technical Assessment for anchoring in cracked and noncracked concrete (Option for concrete screws in sizes 6, 8 and With up to embedment s, it is versatile for high loads or low levels of drilling and installation effort European Technical Assessment for multiple use for nonstructural systems in concrete and precast prestressed hollow core slabs for concrete screws in diameter 6 Approved for use under seismic conditions of category (ø8 to ø for embedment ) Approved for use under fire exposure (R0R1). Small drill hole diameter, small edge and axial g Rid pushthrough installation with an impact screwdriver without torque regulation No curing times, can be loaded iediately Adjustable to compensate for unevenness (Ø8 Ø ) Can be fully removed Wide range of possible plications through numerous variants Visually pealing through different head shes Without assessment, can also be used in compressionresistant natural stone, various solid bricks and green concrete Highly versatile for up to three different embedment s: Embedment 1: low level of drilling and installation effort large clamping thickness reduced loads : medium level of drilling and installation effort medium clamping thickness moderate load Embedment : higher level of drilling and installation effort small clamping thickness heavy loads Not for plications in precast prestressed hollow core slabs 71

After successful installation, if relining is necessary for compensation, this is possible with the concrete screw BSZ (Ø 8 14 ).. If the first lining is not sufficient then it is possible to repeat the adjustment. To do this, once again, the concrete screw must be turned back by a maximum of so that another lining can be fitted.. To do this, when the adjustment is carried out for the first time, the concrete screw must be turned back by a maximum of After the second lining, then remount the fixture in accordance with the installation instructions.. hnom,adj. 2 > hnom The anchor can only be adjusted twice. When doing this the anchor can only be screwed back to a maximum of. In total the lining which is a result of the adjustment must be a maximum of.
