Description

Heavy Hex Lock Nuts NTU Nylon Inserts with Thin Height, Steel Zinc finish — designed for secure, vibration-resistant fastening in demanding environments.

Overview

These NTU nylon insert lock nuts provide reliable locking action thanks to a molded nylon insert that grips the bolt threads. The heavy hex design offers ample wrenching space for high-torque applications while maintaining compact profile with thin height.

Key Features

  • NTU Nylon Insert for vibration resistance and auto-lock performance.
  • Heavy hex shape for improved grip and tool engagement.
  • Thin height reduces protrusion in tight spaces.

  • Size range: 2-4-1/2 (as specified) for versatile use.

Applications

Ideal for machinery, automotive, and equipment assemblies requiring secure fastenings in environments with vibration or motion. The nylon insert locks the nut in place even under dynamic loads, helping prevent loosening and maintenance downtime.
