Product Details

The Seachoice RP-SC1336 is a 5/16-18 stainless steel nylon insert locknut designed for marine and outdoor applications where corrosion resistance is essential. This locknut features a nylon insert ring that creates friction against the bolt threads, providing superior vibration resistance and preventing the nut from loosening under dynamic loads.

Key Features:

  • Thread size: 5/16-18 (5/16 inch diameter, 18 threads per inch)
  • Stainless steel construction for excellent corrosion resistance in marine environments
  • Nylon insert provides self-locking action without requiring additional washers
  • Reusable design maintains locking effectiveness through multiple installations
  • Suitable for boats, trailers, outdoor equipment, and marine hardware
  • Sold in convenient 50-piece bag for multiple projects

Nylon insert locknuts, also known as Nyloc nuts or elastic stop nuts, are ideal for fastening applications subject to vibration, shock loads, or movement. The nylon ring deforms around the bolt threads to create a secure, metal-to-metal connection while preventing self-loosening. The stainless steel material ensures long-lasting performance in saltwater and freshwater environments.
