Professional Applications & Engineering Value

This Grade 5 nylon insert lock nut delivers critical vibration resistance where conventional fasteners fail. The zinc-plated steel construction provides durable corrosion protection while the nylon insert creates consistent friction against bolt threads, preventing loosening under extreme conditions. Engineered with UNC coarse threads and Class 2B thread fit, these 3/8"-16 lock nuts ensure precise engagement and reliable performance in automotive assemblies, industrial machinery, and equipment subjected to continuous vibration. The external hex drive allows for efficient installation with standard tools, making them ideal for maintenance and production environments where downtime must be minimized.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit and UNC coarse thread specifications (3/8"-16). Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations. The Grade 5 strength classification ensures consistent mechanical performance, while the standard hex profile (9/16" width) and external drive style provide universal tool compatibility across industrial applications.
