Twin screw (double thread) EJOT JT3-SB-3x155 / M10x50 DIN 934 for steel substructure PV-06-04

Universal mounting for photovoltaic structures

The EJOT JT3-SB-3x155 / M10x50 double thread is a key mounting element in photovoltaic systems, designed for durability and versatility. Made of stainless steel 1.4301 (A2), it provides corrosion resistance and long-term reliability, even in harsh weather conditions. Its design allows for a safe and stable connection of structural elements with various types of roofing.

This double thread stands out with its dual functionality – it has two threads: one designed for direct mounting in the roof structure, and the other for screwing on adapters with collar nuts. This solution significantly simplifies and speeds up the installation process, eliminating the need for additional connecting elements. It works well both on pitched roofs covered with sheet metal, roofing felt or shingles, as well as when mounting triangles on flat roofs.

The set includes collar nuts and an EPDM gasket, which guarantee a tight connection and prevent water leakage. The integrated EPDM gasket provides additional protection against moisture, which translates into a longer lifespan of the entire installation. Thanks to this, you can be sure that the photovoltaic system will operate flawlessly for many years.
