Product Details

The Seachoice RP-SC3553 is a metric M12-1.75 nylon insert locknut constructed from corrosion-resistant stainless steel. This locknut features a nylon insert that provides vibration resistance and prevents the nut from loosening under stress, making it ideal for marine and outdoor applications where reliability is critical.

Key Features:

  • M12 x 1.75mm metric thread size
  • Stainless steel construction for superior corrosion resistance in saltwater and harsh environments
  • Nylon insert provides self-locking action to prevent loosening from vibration
  • Reusable design allows for multiple installations
  • Marine-grade hardware suitable for boats, PWCs, and outdoor equipment

Nylon insert locknuts are essential fasteners for any marine application where standard nuts would work loose over time. The prevailing torque created by the nylon insert maintains secure fastening even in high-vibration environments. Sold in packages of 25 locknuts per bag.
