• Available in stainless steel A4 and HCR: Ideal for use in reinforced and unreinforced normal concrete and in cracked and non-cracked concrete
• Available in zinc-coated steel, tested to DIN EN ISO 9227 – for corrosion category C5 – 4800hrs
• Can be loaded immediately, with adjustment possible: Time saving.
• Fire rated and ETA approved: Pedigree.
Hex Washer Head
Suitable for helping hand bracket fixings – the washer head gives increase surface area, this is improved with a CFCS A4 washer which stops the brackets spinning on installation, and also gives more surface area for the concrete screw to press against on installation.
Suitable for fire barrier fixings – no washer recommended for this application.
Suitable for some type of U Channel.

Single Fastening Without Fire Exposure
1) The partial safety factor for material resistance from the approval γM=1,5 as well a partial safety factor for load actions γF=1,4 were considered for determining the load.
2) These values apply without influence of the spacing and edge distances
3) C2 only for version zinc plated
