- Environmental regulation compliance meeting RoHS 3 and REACH requirements for safe use across regulated industries
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M30 flange nuts solve critical vibration loosening and corrosion challenges in machinery, structural steelwork, and transportation equipment. The 18-8 stainless steel construction provides inherent resistance to rust and chemical exposure, while the integrated 58mm flange distributes clamping force over a wider surface area, preventing joint fatigue and material deformation. The coarse metric threads (M30 x 3.5mm) ensure rapid assembly in high-vibration environments where fine threads might fail, making these DIN 6331 compliant nuts ideal for construction equipment, agricultural machinery, and marine applications requiring corrosion-resistant fasteners with proven durability.
Specification Summary & Compliance
Manufactured to DIN 6331 standards with Class 6H thread tolerance ensuring precise fit with mating components. The metric coarse thread (M30 x 3.5mm) maintains consistent engagement while the external hex drive (46mm width) provides reliable tooling compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence for global industrial use.
