Professional Applications & Engineering Value
These M20 nylon insert lock nuts provide critical vibration-resistant fastening solutions for industrial machinery, automotive assemblies, and construction equipment where loosening under dynamic loads poses significant safety risks. The zinc yellow-chromate plated steel construction delivers exceptional corrosion resistance in demanding environments, while the Class 8 strength rating ensures reliable performance under heavy loads. The metric coarse thread (M20x2.5) design facilitates quick installation and provides superior resistance to vibrational loosening compared to standard nuts. Engineered to maintain locking integrity up to 220°F maximum temperature, these locknuts solve critical fastening challenges in high-vibration applications across multiple industries.
Specification Summary & Compliance
This M20 x 2.5 mm lock nut features precise Class 6H thread fit tolerance with coarse thread spacing, manufactured to DIN 982 and ISO 7040 international standards. The external hex design (32mm width, 22mm height) ensures compatibility with standard metric tools. Constructed from zinc yellow-chromate plated steel with Class 8 strength classification, these locknuts comply with industrial specifications for heavy-duty applications and meet RoHS and REACH environmental standards.
