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.
  • Steel with zinc finish for corrosion resistance and durability.
  • Size range: 2-4-1/2 (as specified) for versatile use.
