◆UNF Nylon Insert Lock Nut

●Grade 5 — Fine Thread Imperial

▲Zinc Plated Finish

Grade 5 UNF nylon insert lock nuts (nyloc) in zinc plated steel. The nylon collar resists vibrational loosening for Grade 5 UNF fine-thread bolt assemblies in machinery and precision equipment.

Product Highlights −

UNF nylon insert lock nut (nyloc), Grade 5, zinc plated — vibration-resistant locking for Grade 5 UNF fine-thread imperial bolt assemblies.

Nylon insert deforms elastically around the UNF bolt thread, creating prevailing torque resistance against loosening under vibration and dynamic loads.
Grade 5 strength matched to Grade 5 UNF bolts — standard imperial strength for machinery and light structural applications.
UNF fine thread provides additional inherent vibration resistance compared to coarser thread forms, complementing the nylon locking action.
