Product Description Hillman 5/16"-18 zinc-plated nylon insert stop nuts are designed to provide secure and vibration-resistant fastening connections in a wide range of mechanical and construction applications. Commonly referred to as nylon insert lock nuts or Nylock nuts, these fasteners are widely used in equipment assembly, automotive repairs, structural installations, and maintenance projects. Each nut features an integrated nylon insert that grips the threads of the bolt as the nut is tightened. This creates additional friction that helps prevent the nut from loosening due to vibration, movement, or mechanical stress. The locking feature helps maintain consistent clamping force and improves the reliability of the fastening system. These lock nuts are designed to match 5/16"-18 USS coarse thread bolts or threaded rods, ensuring proper compatibility and dependable thread engagement. They can also be used alongside washers of the same size and finish to create a complete fastening system. Manufactured from durable steel, these nuts are finished with a zinc-plated coating that offers moderate protection against rust and corrosion. This corrosion-resistant finish helps maintain hardware performance in general-purpose indoor and light exterior environments. Packaged in a convenient C-Pak containing 100 lock nuts, these fasteners are ideal for contractors, mechanics, builders, and DIY homeowners working on equipment installations, machinery repairs, automotive maintenance, structural assemblies, and general hardware fastening projects. From the Manufacturer The Nylon Insert Lock Nut features an integrated nylon insert that grips bolts to help resist vibration effects. This easy-to-use nut is ideal to securely fasten a bolt when connecting materials.

  • Use for fastening to a bolt when mechanically joining materials
  • Nylon insert for added security to keep nut in place
  • Use with bolt and washer of the same material, finish, and grade
  • Coarse thread for durability
  • Use for any indoor/outdoor projects
