Professional Applications & Engineering Value
This M16 flange nut delivers critical engineering solutions where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel construction provides excellent durability against chemical exposure and atmospheric conditions, while the integrated 31mm flange distributes clamping force over a wider surface area, preventing loosening under dynamic loads. The coarse metric thread (M16x2mm) ensures rapid assembly in heavy machinery, construction equipment, and transportation applications where DIN 6331 compliance guarantees dimensional accuracy and mechanical performance. The external hex drive facilitates high-torque installation, making it ideal for maintenance-critical assemblies requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
Manufactured to DIN 6331 standards with Class 6H thread fit for precise metric threading. Features M16x2mm coarse threads with right-hand orientation and standard hex profile (24mm width/height). The 31mm flange diameter with 5mm thickness provides optimal bearing surface. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
