- Easy installation and removal with standard external hex drive design compatible with common tools
- Precise thread engagement with Class 6H thread fit ensuring consistent performance and reduced cross-threading risk
- Heavy-duty performance in M20 coarse thread configuration providing excellent load distribution
- Environmental compliance meeting RoHS 3 and REACH standards for safe industrial use
- Dimensional stability with 30mm width and 26mm height for consistent performance across applications
Professional Applications & Engineering Value
This M20x2.5 mm 316 stainless steel locknut delivers exceptional engineering value in demanding industrial settings where vibration loosening and corrosion pose significant challenges. The Flex-Top locking mechanism creates consistent friction along the thread engagement, effectively resisting rotational forces that cause conventional nuts to loosen under dynamic loads. Made from premium 316 stainless steel, this locknut offers superior resistance to chlorides, acids, and extreme temperatures compared to standard stainless grades. The coarse thread pitch and Class 6H thread fit ensure rapid installation while maintaining precise tolerances for critical assemblies in machinery, structural frameworks, marine equipment, and chemical processing systems where reliability cannot be compromised.
Specification Summary & Compliance
This metric locknut features M20 thread size with 2.5 mm coarse pitch and Class 6H thread fit per ISO standards, ensuring dimensional accuracy and proper mating with corresponding bolts. The external hex drive design (30mm width, 26mm height) provides standard tool compatibility. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance adherence for industrial applications worldwide.
