MULTI-MONTI®-plus is a result of the systematic further development of HECO's original screw anchor, which is reflected in the technical optimisation of the range and its expansion to include numerous versions, sizes, embedment depths and load classes. As well as satisfying the highest approval standards, the product now offers a considerably higher load-bearing capacity, particularly in the case of tensile loads in cracked concrete. The new screw anchor is therefore suited to all applications that involve high loads – such as high-bay/plant construction or the fixing of pipelines and railings. The MMS-plus version is extremely easy to work with and less susceptible to wear.
New technical design
With its innovative design, the screw anchor offers even greater performance and ease of installation and makes the new features mentioned above possible. The core diameter of the self-tapping screw anchor has been reduced in order to enhance drive performance, even if this hits reinforcements and drill wear is present. At the same time, the outer diameter of the strengthened thread has been increased, which provides a larger surface area in concrete resulting in a higher load-bearing capacity. The optimised screw tip, with its stronger toothed thread and larger outer diameter, now also delivers a considerably improved undercut in concrete. As always, the MMS-plus screw anchor ensures low driving torque and a connection free of expansion pressure. The quality product is easy to recognise thanks to its unique "MMS+" head marking. Highest safety standards for greater versatility HECO has put together an outstanding portfolio of approvals for the MMS-plus. The new screw anchor range has been awarded assessment ETA-15/0784 for cracked and uncracked concrete. This includes the use of concrete screws with two embedment depths per diameter. This means that, depending on application and screw-in depth, a single screw type can now be used to handle different tensile loads and fixture thicknesses. Furthermore, the MMS-plus is also approved for use under seismic impact up to performance category C1. For contractors, these technical advances open up a whole new world of application and construction options with a high degree of safety – not to mention that the higher load-bearing capacity also means fewer mounting points, which in turn leads to big savings in terms of material and time.
