Solar fastening for metal roofs

摘要

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.
