Description
Dual-thread bolt M10x300 with mounting adapter for PV structures
Dual-thread bolt M10x300 with adapter is a complete fastening set designed for solar PV installations on pitched roofs. The double thread — one side for screwing into the timber roof structure, the other a metric M10 thread for securing the adapter — allows mounting rails to be installed without the need for additional fixing elements. The integrated flanged washer with EPDM gasket protects the roof covering penetration point from water ingress, which is essential when installing on metal sheeting, shingles, or roofing felt. The stainless steel adapter with an elongated hole allows the position of the mounting rail to be adjusted, which greatly simplifies precise alignment of the structure on the roof. The set is ready to use straight out of the box — it includes the bolt, adapter, and flange nuts.
Application and mounting advantages
- Fastening aluminium rails on pitched roofs covered with metal sheeting, shingles, or roofing felt
- Mounting triangular structures on flat roofs with a timber substrate
- The EPDM gasket protects the roof covering penetration point against leaks
- Two different threads on a single bolt eliminate the need for additional fasteners
- The elongated hole in the adapter allows the rail position to be adjusted after the bolt is installed
