Professional Applications & Engineering Value

This M20 hex nut delivers critical engineering value by addressing common failure points in heavy machinery, structural frameworks, and automotive assemblies. The Class 10 steel construction provides superior tensile strength to withstand extreme dynamic loads, while the coarse thread design (2.5 mm pitch) ensures rapid assembly and reduced cross-threading risks in high-vibration environments. The DIN 934 standard guarantees dimensional precision for consistent performance across manufacturing and maintenance operations. With external hex drive compatibility, maintenance teams can achieve proper torque values efficiently, minimizing downtime in production facilities, construction sites, and transportation equipment where metric coarse thread fasteners are specified.

Specification Summary & Compliance

This hex nut maintains Class 6H thread fit tolerance per ISO metric standards, ensuring precise engagement with mating components. Manufacturing adheres to DIN 934 specifications for dimensional accuracy (30mm width, 16mm height) and M20 x 2.5 mm coarse thread parameters. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming absence of restricted substances for industrial safety and environmental responsibility.
