Professional Applications & Engineering Value
This heavy-duty hex nut delivers critical engineering solutions where standard fasteners fall short. The extra wide profile (30mm width) significantly increases bearing surface area, effectively distributing clamp load across wider surfaces to prevent material crushing and joint relaxation. Manufactured from high-strength steel with ASTM Grade 2H certification, it maintains preload integrity in high-vibration environments like heavy machinery, structural steel connections, and industrial equipment. The metric coarse thread (M18x2.5mm) with Class 6H tolerance ensures rapid installation while providing sufficient thread depth for optimal strength. DIN 6915 compliance guarantees dimensional accuracy for structural applications requiring precise fastener geometry and proven performance standards.
Specification Summary & Compliance
This M18 hex nut features 2.5mm coarse pitch threading with Class 6H thread fit per ISO metric standards. Manufacturing complies with ASTM A194 and DIN 6915 specifications for dimensional accuracy and material properties. The nut meets ASTM Grade 2H mechanical requirements for heavy-duty applications. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certification. Physical dimensions: 30mm width across flats, 19mm height.
