The double-threaded bolt is a key component used in the installation of photovoltaic systems. Its application includes mounting on various roofing surfaces, such as metal sheets, shingles, or bitumen membranes. A distinctive feature of the double-threaded design is the two different threads at both ends: one, a metal thread, is screwed directly into the roof structure, and the other is used for attaching adapters with flange nuts.

This product is also used for mounting triangles on flat roofs. The double-threaded bolt is supplied with flange nuts and an EPDM washer. The integrated washer and EPDM gasket ensure proper sealing at the connection point.
