Split pin or Cottor pin

A Split Pin (Cotter Pin) is a simple mechanical fastener used to secure bolts, nuts, and other components from loosening. It is inserted through a drilled hole and then bent at the ends to lock the assembly in place, providing a reliable and vibration-resistant locking solution.

Features:

  • Simple and cost-effective locking device
  • Prevents loosening of nuts and bolts
  • Easy installation and removal
  • Good vibration resistance
  • Reusable in low-stress applications
  • Available in multiple sizes and diameters
