Description

Durable Hex Lock Nuts Nylon Insert Grade C Medium Carbon Phosphate Oil 7/16-20 are designed to deliver reliable locking performance in demanding assemblies. Featuring a nylon insert, Grade C medium carbon steel, and a phosphate oil finish, these nuts resist loosening and provide smooth, consistent operation in machinery and equipment.

Key Features

  • Nylon insert locking action: The built-in nylon insert grips the bolt threads to prevent loosening under vibration and dynamic loads.
  • Strong Grade C material: Made from Grade C medium carbon steel for dependable strength in standard mechanical applications.
  • Corrosion-resistant finish: Phosphate oil coating enhances lubricity and protection against rust and wear.
  • Accurate thread size: 7/16-20 hex nut, designed for compatibility with corresponding bolts and fasteners.
  • Standard hex shape: Easy installation with common wrenches or sockets.

Specifications

  • Thread size: 7/16-20 UNC
  • Material: Grade C medium carbon steel
  • Finish: Phosphate oil coating
  • Locking mechanism: Nylon insert
  • Style: Hex lock nut

Applications

These hex lock nuts are suitable for a wide range of applications, including machinery, automotive assemblies, and equipment maintenance—any scenario where vibration or dynamic loads require a secure, reusable locking nut.

Installation Tips

  • Tighten the nut to achieve the locking action; the nylon insert will deform slightly to grip the bolt threads.
  • Ensure threads are clean and free of debris to maximize locking performance.
  • Use with matching 7/16-20 bolts for proper engagement.
