Application Technology

Secure placement on the surface, no dancing or slipping, no sharp edged chips and high assembly speed – these are the properties of the recently expanded EJOFAST^® self-drilling screw range from EJOT.

Now including drilling screws with a diameter of 6mm, the JF3-2-6.0 is particularly useful in the solar sector, for example being used to mount solar substructures on trapezoidal profiles – using short rail systems. Just like all other EJOFAST^® self-drilling screws, the JF3-2-6.0 enables slip-free positioning and chip-reduced screwing, thanks to a particularly finely crafted tip geometry, but with a slightly increased diameter compared to the JF3-2-5.5. The JF3-2-6.0 completes the range of EJOFAST^® self-drilling screws for solar applications and, together with the JF3-2-5.5, forms the perfect team for all applications.

The slim, single-start drill tip does not produce any sharp edged chips that get stuck in the material and have to be laboriously removed. The special thread shape also allows for high assembly speeds, which allows installers to work much more efficiently.

In addition, EJOT has a broad portfolio for solar mounting including the self-drilling EJOT solar fastener with sealing washer and ORKAN dome. The stainless steel connecting element is suitable for mounting PV systems on roofs with trapezoidal profiles, sandwich elements and corrugated fibre cement panels. It transfers all tensile and compressive forces directly into the substructure. The range is rounded off by a selection of sealing elements and adapters.
