PIN (P/N ms9245-25) - New Surplus

The MS9245-25 is a stainless steel cotter pin designed to lock castellated nuts on drilled bolts throughout aircraft structures. With a nominal 1/16-inch diameter, this pin fits standard airframe fastener holes and prevents nut rotation during flight vibration. Install by passing the pin through aligned holes in the bolt and nut, then bending the tines outward to secure.

Commonly used in landing gear assemblies, control surface hinges, and engine mount points where positive mechanical locking is required. Replace with new pins during maintenance rather than reusing; follow FAA AC 43.13-1B procedures for proper installation and safetying technique.
