Having strong structural fasteners is not only needed for compliance with construction regulations but when they meet and exceed the minimum standards it provides peace of mind for users. fischer takes us through some of the new generation of bolt anchors and anchor channel systems that have hit the market and are designed to make construction quicker and easier.

FAZ II Plus >
A new generation of bolt anchors
The fischer Group of Companies is launching its FAZ II Plus bolt anchor. The new addition has a higher assessed (ETA) tensile load-bearing capacity and material strength than the previous generation. The setting process (M8 – M24) is quicker and easier as cleaning the drill hole is unnecessary. There is also a wide range of applications, as the all-rounder product is approved for more construction materials, including concrete, sand-lime brick and steel fibre-reinforced concrete.
// FAZ II Plus was made for transferring high static and medium dynamic loads in cracked and non-cracked concrete. //
FAZ II Plus was made for transferring high static and medium dynamic loads in cracked and non-cracked concrete. The anchors are also suitable for use in sand-lime brick (except for dynamic applications). A general design approval allows anchorages in steel fibre-reinforced concrete with the FAZ II, FAZ II R and FAZ II HCR variants (M6-M24 diameter). Railings, steel beams, pipeline suspensions, cable runs, consoles, facade substructures, wood structures, lifts, conveyor belts, hoists, and many more can permanently and safely be fastened in various construction materials with the anchor.
The new ETA confirms the suitability of diameter versions M16-M24 in galvanised and stainless steel materials for dynamic loads. Compared to the previous generation, the tensile load-bearing capacity has increased, and a higher strength material is processed. This requires fewer fastening points and anchors per application and project, reducing time and cost. An external assessment confirms that the FAZ II Plus’ service life of 120 years is ideal for infrastructure projects and structures designed for a long life span. Regarding applications in seismic regions, the ETA assessment covers seismic performance categories C1 and C2, both with and without the FFD filling disc for filling annular gaps, depending on the diameter.
In addition to aborted holes, compliant installation (ETA) can be carried out. The assessment also covers nuts in accordance with ISO and verifies higher fire resistance values than the predecessor product, with temperatures of up to 1,350 °C with a fire duration of up to 180 minutes according to the RWS fire curve.
Users can process the FAZ II Plus bolt anchor in holes created with a hollow, hammer or diamond drill using pre-positioned, push-through or stand-off installation, depending on the situation. Installation is quicker and easier as there is no need to clean the drill hole. The cone bolt is pulled into the expansion clip by tightening the nut, expanding firmly against the wall of the drill hole. The anchor is then able to carry loads immediately. An additional Dynamic Set makes it easier to safely install dynamic applications. Therefore, FAZ II Plus M16-24 is an efficient fixing solution under dynamic loads with few load changes.
Anchor Channel Systems >
On track for successful fastenings
After the international success of its channel system consisting of anchor channels and T-head bolts, fischer is launching the fixing solution in Germany. The company is also expanding the system with a new generation of InnoLock FES cast-in channels.
Facades, HVAC installations, lifts, machinery, noise barriers and many other applications can be carried out with the system solutions even under high requirements. Cold-formed (FES C) and hot-rolled (FES H) versions of the anchor channel system cover various construction situations and requirements while fastening in cracked and non-cracked concrete together with suitable T-head bolts. The anchor channel system is highly adaptable and flexible, saving time and money while preventing damage to the existing concrete structure.
// fischer offers tailored solutions and curved anchor channels used in specialist constructions such as arched walls or shells. //
The benefits for the use in construction included the reduction in dust as drilling is no longer required. This accelerates the progress of construction while improving health protection, occupational health, and environmental management during projects.
In addition to its regular range, fischer offers tailored solutions and curved anchor channels used in specialist constructions such as arched walls or shells. These solutions also comprise channels with welded anchors and other solutions.
The fully hot-dip galvanised InnoLock FES is now available as an expansion of the range. It is based on a newly developed and patented production method with a lower energy input than hot-rolled anchor channels. The channel is setting new standards in dimensional accuracy and material strength. The wide, robust interlocking between the rail and T-head bolt creates connections that can withstand high loads even along the rail’s longitudinal direction thanks to the locking mechanism. At the same time, the interlocked connections and tightening torque make installation safe, quick and easy.
The patented lip geometry, which features tiered channel lips, provides high retaining values for tensile, shear and longitudinal loads. Thanks to a sophisticated function concept, the T-head bolt remains securely connected to the anchor channel with a flush fit even under maximum loading. A newly developed sealing solution reliably prevents concrete slurry from penetrating the rail during the concreting process, so there is no need to mask the rail on the construction site. The seal was designed so that it can easily be removed before mounting the T-head bolt.
An important aspect for planners and users is that the entire channel system product portfolio is ETA assessed and can be used for designs as per EN 1992-4 and EOTA TR047. fischer also offers the Channel-Fix design software within the fischer FiXperience Suite, a user-friendly method to verify anchor channels. Various combinations consisting of anchor plates, concrete grades, loads, anchor channels and additional reinforcements can easily be modelled and optimised according to a specific fastening scenario. Detailed or short form PDF reports (including formulas) make it easier to check the results.
fischer’s anchor channel system is a versatile, secure and economical fixing solution and as a company, fischer supports planners and users with its in-house design software and service. Providing this comprehensive approach of offering product solutions and services from a single source offers added security and cost-effectiveness when conducting fixing tasks with various requirements.
