Product description
The M12×200 hanger bolt is a high-quality fastener for attaching photovoltaic substructures to roofs with wooden or metal substructures. With an M12 thread, it offers significantly higher holding and tensile strength than smaller dimensions, making it particularly suitable for large or heavily loaded systems.
Made of A2 (1.4301) stainless steel, the hanger bolt is rustproof, corrosion-resistant, and weather-resistant. It has a combination thread: the coarse wood thread in the lower section ensures a secure hold in the rafter, while the metric M12 thread in the upper section allows for the installation of rail holders, adapter plates, or sealing systems.
With a total length of 200 mm, the screw is universally applicable – ideal for standard roofs where stability and precise installation are equally important. Optionally, it can be combined with an EPDM sealing washer to ensure a permanently tight roof system.
Typical applications
- Fastening PV mounting rails to wooden rafters
- Mounting on sheet metal or trapezoidal roofs
- Anchoring adapter plates, brackets, and roof hooks
- Use in PV, solar, and steel structures
