Professional Applications & Engineering Value

Engineered for demanding industrial applications, this heavy-duty hex nut delivers critical performance where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, machinery, and structural assemblies exposed to environmental elements. With its extra-wide profile and Class 10 strength rating, this M12 coarse thread nut effectively distributes clamping forces across wider surface areas, preventing joint loosening in high-vibration environments like automotive chassis, construction equipment, and heavy machinery. The 6H thread fit ensures precise engagement with mating metric coarse thread bolts, reducing installation time while maintaining consistent torque values throughout the assembly process.

Specification Summary & Compliance

This heavy-duty hex nut features precise M12 x 1.75mm coarse thread with Class 6H thread fit tolerance, manufactured to DIN 6915 and ISO 4775 standards. The nut dimensions include 22mm width across flats and 10mm height, providing optimal strength-to-size ratio. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for global industrial applications.
