Professional Applications & Engineering Value

This M5 nylon insert lock nut delivers critical vibration resistance in dynamic applications where loosening under stress compromises safety and performance. The Class 8 steel construction provides exceptional tensile strength for heavy machinery, automotive assemblies, and industrial equipment subjected to constant motion and shock loads. The zinc yellow-chromate plating offers superior corrosion protection in humid or chemically aggressive environments, while the precision metric coarse threading (M5 x 0.8mm) ensures quick installation and reliable engagement. Engineered to DIN 982 and ISO 7040 standards, this locknut maintains consistent locking torque across temperature variations, making it ideal for automotive subsystems, conveyor systems, and manufacturing equipment where vibration-induced failure is not an option.

Specification Summary & Compliance

This locknut features M5 x 0.8mm coarse metric threading with Class 6H thread fit tolerance for precision engagement. The external hex design measures 8mm across flats with a 6.3mm height profile. Manufactured from Class 8 strength steel with zinc yellow-chromate plating for corrosion resistance. Compliant with DIN 982 and ISO 7040 international standards, ensuring dimensional accuracy and performance reliability. The nylon insert maintains locking effectiveness up to 220°F maximum temperature while meeting industry requirements for vibration-resistant fastening solutions.
