Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M20 hex nuts deliver critical performance advantages where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor equipment, machinery assemblies, and structural frameworks exposed to environmental elements. The coarse thread design (2.5mm pitch) ensures faster assembly and reduced risk of cross-threading in high-volume production environments, while the high-profile hex configuration maximizes torque transmission and prevents tool slippage. These metric fasteners are particularly valuable in construction, heavy machinery, and automotive applications where Class 8 strength and reliable clamping force are essential for safety and long-term performance.

Specification Summary & Compliance

This heavy-duty metric fastener features precise M20x2.5mm coarse threads with Class 6H thread fit tolerance, ensuring consistent engagement with mating components. Manufactured to Class 8 strength standards, the nut maintains dimensional stability with 30mm width across flats and 20mm height. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting current environmental standards for industrial components. The right-hand thread direction and external hex drive conform to international metric fastener specifications for universal compatibility.
