Highest guarantees. Products approved
according to the highest quality standards:
- Approved (ETA 20/0046) in option 1 for installation in cracked and non-cracked concrete (C20/25-C50/60).
- Approved (ETA 20/0494) for non-structural redundant systems in concrete (≥ C20/25) and hollow-core slabs (≥ C30/37).
- Approved for fire resistance R30-R120 in concrete.
- Seismic approval C1&C2 for structural installation when there is a risk of some type of seismic movement.
- Maximum performance. Maximum loads recommended in C20/25 to C50/60 cracked concrete and non-cracked concrete. +info
- Allows installation with up to three different screwing depths (in the Ø6 and Ø10 versions). The other measurements are approved for two installation depths. +info
- Allows installation with reduced distances between anchors and at the edge of the concrete element. The anchor, which works using a mechanical interference between the thread and the base material, generates a low load on the concrete.
- Confirmed suitability for the installation of sprinkler systems in accordance with the VdS CEA 4001 guidelines.
Other noteworthy aspects of the product
- Available in a wide range of drill diameters. +info
- Cleaning not necessary. It is not necessary to clean the holes in vertical installations (ceiling and floor).
- Fully removable anchor. Additionally, it can be unscrewed to correctly adjust the installed element. Suitable for use in temporary installations or when it is required to leave the surface completely transparent after disassembly.
- EXPRESS installation. Fast and easy installation. Installation time is reduced because it only requires a drill and an impact driver; the use of torque-controlled torque wrenches is not necessary +info
- INDEX® manufacturing. This allows us to ensure a rigorous control of processes, guarantee the highest quality in our products, provide the best service and obtain a competitive global cost.
- Available in INDEXcal. The INDEXcal anchors calculation programme is the best tool for designers of structural solutions to comply with the requirements of part 4 of Eurocode 2. Quickly and thoroughly check all the anchors in our catalogue based on the parameters entered by the user, indicating whether or not they fit. +info
Manufactured with A4 stainless steel and carbon steel
TXE bimetal fixing
The new TXE fixing model for direct fixing on concrete is manufactured with innovative BIMETAL technology, which offers high resistance to both corrosion and wear during installation.
Firstly, the body of the fixing is manufactured with A4 stainless steel, giving it anti-corrosive properties, up to C5 levels of corrosion. Meanwhile, the tip of the fixing is manufactured in hardened carbon steel, with greater hardness and facilitating the installation and grip on the base material. The innovative production process allows the friction welding of the two materials.

Features of A4 stainless steel
The body of the fixing, manufactured in A4 stainless steel, offers excellent resistance to corrosion and oxidation, up to C5 levels of corrosion. It is suitable for applications in outdoor spaces such as:
- Coastal areas.
- Outdoor spaces with high industrial contamination.
- Areas near roads.
- Tropical and subtropical regions.
Resistance of the steel
The tip of the TXE is manufactured in hardened carbon steel, which allows it to withstand wear on the tip and which makes installation easier while providing the maximum performance.
The tip of the fixing has a key role during the installation. It is the area that starts the threading of the fixing on the base material, generating strong friction and wear. This is the reason that this fixing cannot be made completely from A4 stainless steel, a material with a lower level of hardness than carbon steel.
The blue colour of the tip identifies the area where the fusion of both materials is produced.
Highest guarantees
The fixing has the most prestigious approvals:
- ETA 20/0046 approval for structural fixings in cracked concrete.
- CE certification.
- C1 Seismic approval, suitable for applications in areas with seismic risk.
- Fire Resistance approval, for installations exposed to high temperatures or at risk of suffering a fire.

Design and geometry
Patented double thread, optimised to guarantee maximum loads thanks to the design of a double thread that is embedded deep into the concrete.
The tempered tip ensures greater hardness, durability and ease of installation.
Body of high-resistance steel (stamped carbon steel).
THE/TFE Head: Embossed ribbed washer in hexagonal versions, which ensures a tightness against the base material, preventing the fastening from loosening.
TFF Head. Female thread with double M8/M10 thread, for direct, quick and easy fastening of threaded rods in ceilings (concrete and hollow-core slabs). Suitable for suspension of air conditioning ducts, cable trays, pipe systems, etc.
TFM Head. Male thread, for direct, quick and easy fastening of clamps in concrete and hollow-core slabs.
Head: Includes measurement by length (not in the diameter 5 ones).
Bimetal version. Offers the hardness of a hardened carbon steel tip to facilitate installation, with an A4 stainless steel shaft to provide corrosion protection.
Maximum performance and wide load values
We increased the maximum recommended loads in C20/25 uncracked concrete and C20/25 cracked concrete compared to the previous model.
