Professional Applications & Engineering Value
This nylon insert lock nut delivers critical vibration resistance where conventional fasteners fail. The Black-Oxide 18-8 Stainless Steel construction provides dual protection against corrosion while maintaining structural integrity in humid or chemical environments. The UNC coarse threads with Class 2B fit ensure rapid installation and reliable engagement, reducing assembly time in production lines. Engineered for machinery, automotive, and industrial equipment applications, the nylon insert creates consistent locking torque without damaging mating threads. The 220°F temperature rating makes it suitable for engines, motors, and equipment experiencing thermal cycling, while the external hex design accommodates standard wrenching tools for maintenance accessibility.
Specification Summary & Compliance
This lock nut features 1/2"-13 UNC coarse threads with Class 2B thread fit per ASME B1.1 standards, ensuring precise dimensional accuracy and interchangeability. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and substance restriction adherence. The external hex drive (3/4" width) and standard profile (19/32" height) maintain compatibility with industrial fastener systems while the nylon insert provides consistent locking performance within specified temperature limits.
