Concrete anchor M8x115/65 Zn is used to fasten fence columns 60x40mm to a concrete base with the help of a plate. If we have an existing concrete base, we do not need to dig holes and concrete the columns into the ground, but we fix the columns directly to the plate with a concrete anchor. The minimum anchoring depth is 5mm. For fences over 160 cm, it is necessary to use chemical anchors.
