Solar fastening for metal roofs

The new EJOT solar fastener JT3-SB-3-8.0xL combines the high bearing capacity of EJOT solar fasteners with the fast installation speed of a self-drilling screw. A special hardened drilling tip at the lower end of the fastener allows the installation of the fastener into high strength steel substructures with a maximum thickness of 3mm (1/8") without pre-drilling. EJOT solar fastener JT3-SB-3-8.0xL is designed for fixing solar systems on sandwich elements and trapezoidal sheets. The transmission of all loads into the substructures prevents damage of the roof after the installation. For high corrosion resistance, all bearing parts of the new fastener are made of stainless steel AISI 304 (A2). For special applications, a version out of stainless steel AISI 316 (A4) will also be available.
