Professional Applications & Engineering Value
This M30 left hand thin hex nut delivers critical engineering solutions where reverse threading prevents accidental loosening from rotational forces. The 18-8 stainless steel material provides excellent corrosion resistance in chemical processing, marine, and food industry applications, while the extra fine 1.5mm thread pitch offers superior vibration resistance and precise adjustment capabilities. The thin DIN 439B profile enables installation in confined spaces without compromising strength, making it ideal for machinery, automotive, and precision equipment requiring left-hand thread security. The combination of Class 6H thread fit and external hex drive ensures reliable performance in high-stress industrial environments where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to DIN 439B standards with Class 6H thread fit tolerance for precise metric threading. Features M30x1.5mm left-hand extra fine threads with 46mm width and 15mm height dimensions. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring adherence to international safety and substance restriction requirements for industrial components.
