Professional Applications & Engineering Value
This 7/16"-20 UNF nylon insert locknut delivers critical vibration resistance where conventional fasteners fail. The Black-Oxide 18-8 Stainless Steel construction provides dual protection against corrosion and galling, while the nylon insert locking mechanism maintains clamp force under extreme vibration and thermal cycling up to 220°F. Engineered with Class 2B UNF fine threads, this locknut ensures precise fitment in automotive, machinery, and industrial equipment applications where vibration-resistant fastening is essential for operational safety and reduced maintenance intervals. The external hex drive facilitates quick installation in confined spaces without compromising torque application.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit for consistent engagement. Features 7/16"-20 UNF fine threading with right-hand direction and standard hex profile (5/8" width). Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency.
