Professional Applications & Engineering Value
This 10-32 nylon insert locknut delivers exceptional engineering value through its black corrosion-resistant steel construction and advanced locking technology. The UNF fine thread configuration provides superior resistance to loosening under vibration, making it ideal for automotive assemblies, machinery, and electrical enclosures where vibration resistance is critical. The nylon insert creates consistent friction against mating threads, eliminating the need for secondary locking devices while maintaining temperature stability up to 220°F. This combination of corrosion-resistant coating and precision Class 2B thread fit ensures reliable performance in harsh industrial environments, reducing maintenance frequency and improving equipment reliability.
Specification Summary & Compliance
This locknut features 10-32 UNF fine threads with Class 2B thread fit for precise dimensional accuracy. The external hex drive measures 3/8" across flats with a 15/64" height profile. Manufactured to industrial standards with nylon insert locking technology rated for temperatures up to 220°F. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance.
