Professional Applications & Engineering Value
This M30 left-hand thread hex nut delivers exceptional engineering value through its specialized 316 stainless steel composition and thin profile design. The extra fine 1.5mm pitch metric thread provides superior resistance to vibration-induced loosening, making it ideal for rotating machinery, conveyor systems, and precision equipment where reverse-thread applications are critical. The corrosion-resistant properties of 316 stainless steel ensure reliable performance in marine, chemical processing, and outdoor applications where exposure to moisture and corrosive elements would compromise ordinary fasteners. The external hex drive design facilitates easy installation and removal with standard tools, while the Class 6H thread fit maintains precise tolerances for consistent clamping force in demanding industrial environments.
Specification Summary & Compliance
This thin hex nut features M30 x 1.5mm left-hand metric threads with Class 6H thread fit tolerance and dimensions conforming to DIN 439B and ISO 4035 standards. The nut measures 46mm across flats with a 15mm height profile. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
