The SPAX concrete screw range
Concrete screws are the ideal choice for fast, secure and economical fastening directly into concrete. Thanks to different head shapes, we offer optimal adaptation and maximum flexibility for indoor use. Of course, the screws are approved according to ETA 20/0859 and ETA 20/0884 for use in cracked and uncracked concrete as well as for multiple fasteners (cable ducts). Our galvanized concrete screws can be adjusted twice for a total of 10 mm.
They offer a fire resistance of up to 120 minutes and may be used in Germany for the attachment of sprinkler systems. In addition, they can be used in the seismic performance categories C1 and C2 and ensure the smallest edge and axle distances thanks to a spreading pressure-free anchorage. Another practical advantage: Due to different binding depths, one and the same screw can be used for different attachment thicknesses.
