Professional Applications & Engineering Value

This 316 stainless steel flex-top locknut is engineered to address critical challenges in industrial settings where vibration loosening and corrosion compromise fastener integrity. The flex-top locking mechanism creates consistent friction on the bolt thread, effectively resisting loosening under dynamic loads in machinery, automotive, and electrical enclosures. Made from 316 stainless steel, it offers excellent resistance to chlorides and acidic environments, making it suitable for chemical processing, marine, and outdoor applications. The M5 coarse thread with 0.8mm pitch ensures quick assembly and reliable performance in metric-based systems, while the external hex drive allows for high-torque installation with common tools. This combination of locking type and material durability reduces maintenance frequency and enhances safety in vibration-prone industrial applications.

Specification Summary & Compliance

This locknut features M5 metric coarse thread with 0.8mm pitch and Class 6H thread fit per ISO standards, ensuring precise dimensional accuracy and reliable performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally sensitive and regulated industrial applications. The nut is manufactured to standard external hex drive specifications with dimensions of 8mm width and 7.5mm height, providing consistent quality across production batches.
