Professional Applications & Engineering Value
This M2.5 nylon insert locknut delivers critical vibration resistance in demanding industrial applications where constant motion and mechanical stress threaten fastener integrity. The 316 stainless steel construction provides exceptional corrosion resistance, making it ideal for marine, chemical processing, and outdoor equipment where moisture and corrosive elements are present. The nylon insert locking mechanism creates consistent friction against mating threads, maintaining secure fastening without damaging threads. With its coarse metric thread and Class 6H thread fit, this locknut ensures quick assembly and reliable performance in automotive components, electrical enclosures, machinery, and precision equipment where vibration-induced loosening could lead to operational failure or safety hazards.
Specification Summary & Compliance
This metric hex locknut features M2.5 thread size with 0.45mm coarse pitch and Class 6H thread fit tolerance per ISO standards. Manufactured to DIN 985 specifications with standard external hex drive (5mm width) and 3.8mm height profile. The locking mechanism utilizes a nylon insert rated for maximum temperature of 220°F. Compliance includes REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring safe use across industrial sectors without hazardous substance restrictions.
