Professional Applications & Engineering Value
This M20 nylon insert lock nut delivers critical vibration resistance in demanding industrial applications where loosening under dynamic loads poses significant safety risks. The 316 stainless steel construction provides exceptional corrosion resistance, making it ideal for marine environments, chemical processing equipment, and outdoor infrastructure exposed to harsh weather conditions. The coarse thread pitch (2.5 mm) ensures rapid installation and superior resistance to vibration-induced backing off, while the nylon insert maintains consistent locking force up to 220°F. Engineered to DIN 982 standards with external hex drive, this locknut offers reliable performance in machinery, automotive assemblies, and structural applications where vibration damping and corrosion protection are paramount.
Specification Summary & Compliance
This metric M20x2.5 mm lock nut features Class 6H thread fit tolerance for precision engagement, manufactured according to DIN 982 standards with standard external hex profile (30mm width, 22mm height). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
