Professional Applications & Engineering Value

This 1 1/8"-12 UNF nylon insert lock nut delivers exceptional engineering value in applications where vibration-induced loosening poses significant operational risks. The ASTM Grade C steel construction provides the necessary tensile strength for heavy machinery, automotive assemblies, and industrial equipment subjected to constant stress and dynamic loads. The extra-wide thin profile offers a critical advantage in space-constrained installations while maintaining full locking performance. The fine thread spacing and Class 2B thread fit ensure precise engagement with mating components, reducing the risk of cross-threading and providing consistent clamping force. The nylon insert locking mechanism effectively dampens vibrations without compromising the integrity of the right-hand thread system, making it ideal for applications requiring repeated disassembly and reassembly while maintaining reliable performance up to 250°F.

Specification Summary & Compliance
