Screw anchors for mounting building components on stone and concrete

Screw anchors are increasingly used in construction for mounting building components on concrete and stone because screw anchors can be processed faster than mechanical and chemical anchors. HECO-Schrauben spends a lot of time in its R&D department testing and further developing its screw anchors, which are marketed under the name MULTI-MONTI-Plus. The company has introduced many new versions that are approved for use in various concrete and stone types and for various applications.

Screw anchors have distinct advantages over mechanical and chemical anchors. Screw anchors are significantly cheaper and save a lot of time during installation thanks to their easy and fast processing. Screw anchors have reinforced serrations at the screw tip and special threads that cut into the concrete. Only a hole needs to be drilled, which can be cleaned by moving the drill bit in and out of the hole a few times. After screwing in, the screw anchor can be loaded immediately.

Concrete and stone types

Screw anchors can handle very high loads. They were initially used primarily in hard stone and cracked or uncracked concrete, but thanks to innovations and new approvals, they can now also be used for fixings in sand-lime brick, aerated concrete, brick and hollow-core slabs. With HECO's HCS 4.0 calculation software, the load and dimensioning of HECO screw anchors can be calculated. Based on the information about the project, substrate and conditions, a recommendation with 3D graphics rolls out for the optimal screw connection, screw type, dimensions and quantity required.

Applications

Screw anchors can be used for mounting cable trays, light fixtures, solar panels, facade panels, pipe systems, railings, crash barriers and noise barriers, among other things. Thanks to their stability in the event of fire, resistance to corrosion and easy (dis)assembly for inspections, they are also suitable for fixing fire-resistant boards in tunnels. Some screw anchors are approved for multiple use; for example, in the (temporary) fixing of fall protection, braces, formwork, scaffolding and supply lines on the construction site. With a simple tool, a construction company can test whether the anchor shows wear and tear and should no longer be used.

HECO screw anchors

HECO-Schrauben has an extensive range of 25 types of screw anchors. In addition to the "normal" screw anchors, the MMS-plus V pre-piercing anchor is available for mounting fences and railings. For temporary fixings, the MMS-plus SSK has been developed and for mounting wooden elements on concrete, one can choose from the MMS-plus S or the MMS-TC. Various head types such as hexagonal head, round head, eye anchor and internal and external threaded anchor allow the fixing of mounting rails and pipes.

HECO's MULTI-MONTI-Plus are approved for fire exposure (in accordance with R120 and RWS 180) and for use in earthquake zones (category C1 and C2). In addition, they comply with the VdS directive CEA 4001 for the installation of sprinkler systems.
