Professional Applications & Engineering Value

This black-oxide steel flange locknut delivers critical vibration resistance where conventional fasteners fail. The serrated locking design bites into mating surfaces, creating permanent resistance to rotational loosening in high-vibration environments like heavy machinery, automotive assemblies, and structural frameworks. The integrated 1 1/32" flange eliminates separate washers while distributing clamp load over wider areas, preventing surface damage to soft materials. Manufactured with UNC coarse threads and Class 2B thread fit, it maintains consistent engagement in challenging applications where thermal cycling and dynamic stresses compromise standard fasteners. The external hex drive ensures straightforward installation with common tools, reducing assembly time in industrial maintenance and production lines.

Specification Summary & Compliance

This flange locknut features 1/2"-13 UNC coarse threads with Class 2B thread fit for reliable engagement. The black-oxide steel construction provides corrosion resistance while maintaining mechanical strength. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
