Professional Applications & Engineering Value

This 6-32 nylon insert locknut delivers critical vibration-resistant performance for industrial assemblies subject to constant motion and stress cycles. The black-oxide 18-8 stainless steel construction provides dual protection against corrosion and galling, while the nylon insert locking mechanism creates consistent friction that prevents loosening without damaging mating threads. Engineered with Class 2B UNC coarse threads, this locknut ensures rapid installation in manufacturing environments while maintaining precise thread engagement. The 220°F temperature rating makes it suitable for automotive, machinery, and electrical enclosures where thermal expansion occurs. The external hex drive allows for high-torque installation using standard tools, making it ideal for maintenance and production lines requiring reliable, reusable fastening solutions.

Specification Summary & Compliance

This locknut features Class 2B thread fit per UNC standards with 6-32 coarse threading and 5/16" hex width. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The nylon insert locking system maintains performance within specified temperature ranges while the black-oxide surface treatment enhances corrosion resistance without compromising dimensional accuracy.
