Product Details

The Seachoice RP-SC3516 is a premium quality M8-1.25 nylon insert locknut manufactured from corrosion-resistant stainless steel. This metric locknut features a nylon insert that creates a prevailing torque locking mechanism, preventing the fastener from loosening under vibration or dynamic loads commonly encountered in marine, automotive, and outdoor applications.

Key Features:

  • M8 x 1.25mm metric thread size for precise fitment
  • Stainless steel construction provides excellent corrosion resistance in marine and harsh environments
  • Nylon insert locking mechanism prevents loosening from vibration without requiring lock washers
  • Reusable design allows for multiple installations while maintaining locking effectiveness
  • Packaged 50 pieces per bag for convenient bulk quantity

Ideal for securing critical fasteners on boats, trailers, marine equipment, and outdoor hardware where moisture exposure and vibration resistance are essential. The nylon insert locknut design eliminates the need for separate locking washers while providing superior holding power compared to standard hex nuts.
