MULTI-MONTI®-plus: HECO screw anchor with ETA
16 March 2017
The new screw anchor MULTI-MONTI®-plus (MMS-plus) from HECO for cracked and non-cracked concrete, comes complete with a European Technical Assessment and offers a range of innovative features that HECO says delivers technical advantages, as well as a whole new range of application options.
Including the use of concrete screws with two embedment depths per diameter, the new screw anchor range has been awarded a European Technical assessment (ETA – 15/0784) for cracked and non-cracked concrete. 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 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.
MMS-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.
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.

Who will be Fastener Technology Innovator 2017?
One of the many attractions of Fastener Fair Stuttgart is the first-hand opportunity to assess new products and services that exhibitors have brought to the market since the last show.
Fastener + Fixing Magazine will once again, sponsor the Route to Fastener Innovation Competition. We'll be posting two entries a day leading up to the show – remember to take a note of the stand numbers and attend the special presentation on the final day of the show - where one of these products will be awarded the title of 'Fastener Technology Innovator 2017.'
