Professional Applications & Engineering Value

This M4 nylon insert locknut delivers critical vibration resistance in demanding industrial applications where loosening under dynamic loads is a major concern. Manufactured from 316 stainless steel, it offers exceptional resistance to corrosion from chemicals, moisture, and salt spray, making it ideal for marine, chemical processing, and food industry equipment. The coarse metric thread (M4 x 0.7mm) and Class 6H thread fit provide reliable engagement and ease of assembly, even in blind or hard-to-reach locations. The nylon insert creates consistent friction along the external hex drive threads, maintaining clamp load without damaging mating surfaces. By conforming to DIN 982 specifications, this locknut ensures dimensional consistency and performance reliability in automated assembly systems and high-vibration machinery, effectively preventing costly downtime and maintenance.

Specification Summary & Compliance

This locknut features an M4 x 0.7mm coarse metric thread with Class 6H thread fit per ISO standards, ensuring precise dimensional accuracy. It is manufactured in compliance with DIN 982 for dimensional and mechanical properties. The product is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental directives, confirming the absence of restricted hazardous substances. The nylon insert is rated for continuous service up to 220°F maximum temperature.
