Description

Hex Lock Nuts NM NE Nylon Inserts 18/8 Stainless 5/40 are a reliable locking solution for stainless steel assemblies. Featuring a nylon insert for vibration resistance and a corrosion-resistant 18/8 stainless steel body, these hex lock nuts are designed to keep critical fastenings secure in demanding environments.

Product Overview

These nylon insert lock nuts (often called Nylock nuts) combine a standard hex nut with a molded nylon insert that generates friction to prevent loosening due to vibration, shock, or dynamic loads. The 18/8 stainless steel construction (304 stainless) ensures excellent corrosion resistance and long-lasting durability across a wide range of applications.

Key Features

  • Nylon insert lock design: Provides a positive locking action that resists loosening under vibration and impact.
  • Material: 18/8 stainless steel (304): High corrosion resistance and strength for challenging environments.
  • Hex geometry: Standard hex profile for easy tightening with common tools and even load distribution.
  • Thread size: 5/40: Fits applications requiring 5/40 inch thread.
  • Reusable and durable: Maintains locking performance over multiple install/removal cycles.

Applications

Ideal for mechanical assemblies, automotive components, industrial equipment, marine and water-resistant settings, and general engineering projects where vibration resistance and reliable locking are essential.
