For pre-positioned installation, the positions of the boreholes must be very precise, since the through holes are specified in the add-on part.

These complex conditions are an ideal case for using the EJOT FDS® screw (Flow Drill Screw). Additional processing steps such as pre-drilling, stamping or thread-cutting are no longer necessary. Thanks to the increased thread engagement of the FDS® screw in the formed extrusion, a high-strength screw joint without any chips is created.

For applications on corrugated fibre cement sheets, we recommend the set with an FDZ fibre cement seal. The main benefit is that all tensile and compressive forces are transferred directly into the substructure.

The advantages at a glance Anchoring in reduced concrete panel thickness: M8 (80 instead of 100 mm) and M10 (100 instead of 120 mm) More flexibility for different add-on part thicknesses through second installation depth in diameters M8, M10 and M12 Seismic performance values C2 in diameters M8 - M16 Increased installation safety through coloured setting depth marking.

09.03.2022, Construction Division The new EJOFAST® JF3-Plus adds a powerful product to the proven EJOFAST® self-drilling screw range from EJOT.

The rear ventilation gap created between the cladding material and the insulating material not only gives the rear-ventilated facade its name, but also adds key structural-physical advantages.

EJOT micro screws at a glance: High economic efficiency through direct assembly Compact dimensions: for the assembly in small installation space No need for additional inserts or add-ons Reduction of cycle times or omission of complete work steps Suitable for manual and automated assembly Recyclable thanks to removable connection Different thread geometries for the direct assembly into plastic or metal; metric threads also available

Advantages: Easy assembly (no setting tools, exception: drop-in anchors) Immediate load-carrying capacity (no curing times) Self-locking load bearing capacity: As soon as load is introduced via the add-on part, the cone bolt continues to pull into the sleeve.

Together, these two thicknesses give us the required clamping length. If you add the grip length and the installation depth together you get the total length.

Wherever maximum assembly reliability and performance are required, the flow drill FDS® screw, which is already used for the body-in-white construction, can fully demonstrate its advantages.

The prognosis program DELTA CALC® and ALtra CALC® for predesigning joints in thermoplastics and light metals will spare expensive experiments with your components; you will save time and minimize costs. The new Application Checks for FDS® screws, thermal adhesive bonding boss EJOT TSSD® and the friction welding process EJOWELD® offers you possibilities to determine benchmarks and to prove the feasibility of the respective joining task.
