Professional Applications & Engineering Value
This 3/8"-24 UNF serrated flange lock nut addresses critical vibration-induced failure points in industrial machinery, automotive assemblies, and heavy equipment. The 18-8 stainless steel construction provides exceptional corrosion resistance while maintaining mechanical strength in demanding environments. Precision-engineered serrations create permanent locking action by embedding into contact surfaces, eliminating the need for secondary locking devices. The integrated flange distributes clamping force over a wider area (3/4" diameter), preventing surface damage and maintaining joint integrity. With UNF fine threading and Class 2B thread fit, this fastener delivers reliable performance in applications requiring precise torque control and repeated disassembly cycles.
Specification Summary & Compliance
This flange lock nut features 3/8"-24 UNF fine threads with Class 2B thread fit per ASME standards, ensuring precise dimensional accuracy and reliable thread engagement. The 3/4" flange diameter and 0.12" flange thickness provide optimal load distribution. Manufactured from 18-8 stainless steel with external hex drive and right-hand threading. Fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations for industrial use worldwide.
