Professional Applications & Engineering Value

This M39x4mm hex nut delivers critical performance in demanding applications where corrosion resistance and mechanical strength are paramount. Manufactured from 316 stainless steel, it effectively resists chloride-induced stress corrosion cracking, making it ideal for marine, chemical processing, and offshore installations. The coarse metric thread (4mm pitch) facilitates quick installation and is less prone to fouling in dirty or high-vibration environments compared to fine threads. Its compliance with the DIN 934 standard guarantees dimensional precision, ensuring reliable mating with corresponding Class 6H bolts for structural connections, heavy machinery, and infrastructure projects requiring long-term, maintenance-free service.

Specification Summary & Compliance

This hex nut conforms to DIN 934 specifications with a Metric M39 coarse thread (4mm pitch) and Class 6H thread fit tolerance. Key dimensions include a width across flats of 60mm and a height of 31mm. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious industrial supply chains.
