Professional Applications & Engineering Value
This M4 nylon insert lock nut delivers critical vibration resistance in demanding industrial environments where 316 stainless steel provides essential corrosion protection against chemicals, saltwater, and atmospheric exposure. The nylon locking element creates consistent friction against the bolt thread, eliminating the need for secondary locking devices and reducing assembly time. With its coarse metric thread (M4 x 0.7mm) and Class 6H thread fit, this external hex locknut ensures precise engagement in automotive, marine, food processing, and chemical equipment applications. The 220°F maximum temperature rating makes it suitable for engines, motors, and heated industrial systems where thermal cycling would compromise inferior fasteners.
Specification Summary & Compliance
This metric locknut features M4 x 0.7mm coarse right-hand threads with Class 6H thread fit tolerance, manufactured to DIN 985 standards for dimensional consistency. The standard hex profile measures 7mm across flats with 5mm height. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance adherence for global industrial applications.
