Professional Applications & Engineering Value
This 12-24 UNC locknut with external-tooth lock washer addresses critical vibration-induced loosening challenges in industrial machinery, automotive assemblies, and heavy equipment. The 18-8 stainless steel construction provides excellent corrosion resistance while maintaining structural integrity in demanding environments. The integrated 400 stainless steel washer creates positive locking action through its external teeth that bite into mating surfaces, preventing rotation under dynamic loads. The coarse thread design ensures rapid installation and removal while the Class 2B thread fit guarantees consistent performance across production runs. This combination makes it ideal for applications where vibration resistance and long-term reliability are paramount concerns.
Specification Summary & Compliance
This heavy-duty locknut features 12-24 UNC coarse threads with Class 2B thread fit precision, right-hand thread direction, and standard external hex drive. Dimensions include 7/16" width across flats and 11/64" height. The assembly combines an 18-8 stainless steel nut with 400 stainless steel external-tooth lock washer (0.5" OD). Manufacturing complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental standards, ensuring regulatory compliance for industrial applications worldwide.
