Professional Applications & Engineering Value
This heavy-duty nylon insert lock nut delivers critical vibration resistance in demanding industrial environments where mechanical fasteners face constant stress cycles. The black corrosion-resistant coated steel construction provides durable protection against environmental factors, making it ideal for outdoor equipment, machinery, and automotive applications. The extra-wide thin profile offers superior wrenching surface while maintaining a low-profile design for space-constrained assemblies. With UNC coarse threads and Class 2B thread fit, this locknut ensures reliable engagement and disengagement without galling or cross-threading. The nylon insert locking mechanism maintains consistent clamping force even under extreme vibration, eliminating the need for secondary locking devices and reducing maintenance costs in industrial systems.
Specification Summary & Compliance
This locknut features precision 3/8"-16 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring proper engagement with mating components. The external hex drive measures 11/16" across flats with a 13/32" height for the extra-wide thin profile. Manufactured from steel with black corrosion-resistant coating and nylon insert rated to 250°F maximum temperature. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
