The MULTI-MONTI®-plus A4 (MMS-plus A4) screw anchor is an enhancement of the MULTI-MONTI® A4 concrete screw. It is driven directly into a predrilled hole without a dowel and has load-bearing strength right from the word go. The reinforced toothing on the screw tip cuts an internal thread in the material during insertion. This creates a positive locking connection, which is subsequently used for the anchoring. This not only facilitates the installation procedure, but also guarantees the craftsman a high level of application safety. The MULTI-MONTI®-plus A4 concrete screw can be driven in close to the edge and without a torque wrench and is completely removable.
