Description
EJOT JT3-SB-3x155 – stainless steel double-thread bolt M10x50 for PV mounting structures
EJOT JT3-SB-3x155 double-thread bolt is a professional fastening element designed for installing photovoltaic mounting structures on roofs covered with metal panels, sheet metal, shingles or roofing felt. Made of stainless steel 1.4301 (A2), it ensures a durable and corrosion-resistant connection in all weather conditions. The double-thread design combines two functions in one element — the end with a self-tapping thread screws directly into the steel roof structure, while the opposite end with a metric M10 thread serves as a mounting point for adapters using flange nuts. The total working length is 185 mm, allowing for secure anchoring even in thicker layers of roof covering. The double-thread bolt is supplied complete with flange nuts and an EPDM washer, which effectively seals the roof penetration point, protecting against leaks.
Key benefits for the installer
- Complete mounting set — DIN 934 flange nuts and EPDM washer included, no need to order additional components
- Austenitic A2 (grade 304) stainless steel with added nickel provides exceptional resistance to corrosion and mechanical stress, with no risk of rust even after years of use
- Universal application — roofs with metal panels, sheet metal, shingles, roofing felt, as well as installation of triangles on flat roofs
- Integrated flange washer with EPDM seal guarantees tightness at the point of penetration through the roof covering
- M10 metric thread compatible with standard adapters and PV mounting systems
