Professional Applications & Engineering Value
This heavy-duty M30 flange nut is engineered to solve critical challenges in industrial assembly. Manufactured from 316 stainless steel, it offers exceptional resistance to corrosion from chemicals, saltwater, and extreme weather, making it a reliable choice for marine, chemical processing, and outdoor infrastructure. The integrated flange distributes clamping force over a wider area, preventing surface damage and maintaining joint integrity under high vibration and dynamic loads. Its coarse metric thread and Class 6H fit ensure rapid assembly and a secure hold, reducing the risk of failure in structural frameworks, heavy machinery, and transportation equipment. This nut delivers long-term durability and performance where standard fasteners fall short.
Specification Summary & Compliance
This flange nut conforms to DIN 6331 specifications, featuring an M30 thread size with a 3.5mm coarse pitch and a Class 6H thread fit for precision. Key dimensions include a 58mm flange diameter, 8mm flange thickness, and a 46mm hex width. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial components.
