Professional Applications & Engineering Value
This M5 left-hand thread hex nut solves critical reverse-rotation challenges in machinery where standard right-hand threads would loosen under counter-clockwise motion. The black-oxide steel surface treatment provides superior corrosion protection compared to plain steel, while the thin profile (2.7mm height) enables installation in compact assemblies where standard nuts would interfere. Engineered with Class 6H thread tolerance, this metric fastener maintains precise engagement with mating components, preventing vibration-induced loosening in automotive, manufacturing, and equipment applications. The coarse 0.8mm pitch facilitates quick assembly and disassembly while providing sufficient thread engagement for reliable performance in industrial settings.
Specification Summary & Compliance
This thin profile hex nut features M5x0.8mm left-hand coarse threads with Class 6H thread fit per ISO standards. Manufactured to ASTM A108, DIN 439B, and ISO 4035 specifications with dimensional accuracy of 8mm width and 2.7mm height. Compliant with RoHS 3 (2015/863/EU) with exemption 6(a) for lead as steel alloying element and REACH (EC 1907/2006) regulations as of January 2023. Rated Class 04 for consistent mechanical performance in industrial fastener applications.
