Hirobo HI2509015 10-Pack Roll Pins 2 x 12 for RC Helicopter Maintenance  [HI2509015]

Roll pins designed for transverse retention

The Hirobo HI2509015 roll pin 2 x 12 is distributed as a 10-piece pack for RC helicopters and similar model airframes where a transverse roll pin is required to secure components axially.

They are typically used to lock shafts, hold fine linkages, and retain small assemblies where a non-threaded pin is preferred. The 2 x 12 size denotes the approximate diameter and length, informing your choice of a replacement that fits existing apertures without modification.

To install, line the pin with the hole and press or tap it evenly until properly seated; it will act as a simple retention device resisting axial movement in rotor parts and control linkages. Store spare pins for routine servicing and component rebuilds.
