Professional Applications & Engineering Value

This M16 left-hand thread hex nut with 2mm coarse pitch addresses critical engineering challenges in applications where standard right-hand threads would loosen under counter-clockwise rotation forces. The thin DIN 439B profile provides significant space savings in compact assemblies while the 18-8 stainless steel construction ensures long-term reliability in corrosive environments. Particularly valuable in rotating machinery, conveyor systems, and safety-critical equipment, this left-hand metric fastener prevents accidental disassembly in applications subject to reverse torque. The Class 6H thread fit maintains precise tolerances for consistent performance across industrial applications requiring reliable left-hand fastening solutions.

Specification Summary & Compliance

This thin hex nut features M16x2mm left-hand metric threads with coarse spacing and Class 6H thread fit per ISO standards. Manufactured to DIN 439B specifications with 24mm width and 8mm height dimensions. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for industrial applications worldwide.
