M10×300 mm A2 Double-Threaded Bolt for PV Adapters and Triangles with EPDM Washer
The M10×300 mm double-threaded bolt made of A2 (1.4301) stainless steel is a key mounting component in photovoltaic systems installed on pitched roofs. Its design with two different thread types allows one end to be screwed directly into the timber roof structure (rafters), while the other end — with an M10 metric thread — is used to fasten roof adapters or triangles on flat roofs. The bolt is sold as a complete set with flange nuts and an EPDM washer, which seals the point where it passes through the roof covering — eliminating the risk of leaks. The austenitic stainless steel guarantees exceptional corrosion resistance in all weather conditions, which is particularly important given years of exposure to rain, snow and UV radiation.
Advantages and application
- Dual thread — a threaded end for screwing into timber, and a metric end for mounting adapters with flange nuts
- Integrated flange washer with EPDM seal ensures a watertight connection with the roof covering
- Universal application — roofs covered with metal roof tiles, trapezoidal sheet, shingles or roofing felt
- Long-lasting resistance to weather conditions — rain, snow, UV, marine and industrial environments
- Complete ready-to-install set — bolt, flange nuts and EPDM washer in one package
The M10×300 double-threaded bolt is designed for installing photovoltaic structures on pitched roofs. The threaded end screws directly into the rafter or roof batten, while the mounting adapter or triangle is fitted onto the metric end. Flange nuts with an EPDM washer ensure secure clamping and watertightness of the connection across the entire contact surface with the roof covering. It's a ready-made solution that speeds up roof installation work — a single tool is all that's needed to secure the bolt into the timber structure and protect the anchoring point.
