Professional Applications & Engineering Value
These M2 nylon insert lock nuts solve critical vibration-induced loosening problems in industrial machinery, automotive assemblies, and electronic enclosures. The zinc-plated steel construction provides essential corrosion resistance while the nylon insert locking mechanism creates consistent friction against the mating metric thread, eliminating the need for secondary locking devices. With coarse threading and Class 6H thread fit, installation is streamlined while maintaining precision alignment. The external hex drive style allows for standard tooling compatibility, reducing assembly time and tooling costs in high-volume production environments where vibration resistance and thermal stability up to 220°F are critical performance requirements.
Specification Summary & Compliance
This locknut features M2 x 0.4 mm coarse metric threading with Class 6H thread fit tolerance ensuring precise engagement. Manufacturing complies with DIN 985 and ISO 10511 standards for dimensional accuracy and performance. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, confirming adherence to environmental regulations. With dimensions of 4mm width and 2.8mm height, these Class 8 strength lock nuts provide reliable fastening solutions for industrial applications demanding high vibration resistance and thermal stability.
