Hirobo HI2509015 Roll Pin 2 x 12 10pc Replacement for RC Helicopter Parts  [HI2509015]

Small-batch roll pins for shaft retention

The Hirobo HI2509015 roll pin 2 x 12 is supplied in a 10-piece batch for use in RC helicopters and other model airframes where a compact roll pin is required to prevent axial movement.

Common applications are securing rotor shafts, retaining small control linkages, and locking parts where a transverse pin is the preferred retention method. The 2 x 12 label refers to the pin's nominal diameter and length, which guides selection of a compatible replacement without altering adjacent parts.

Fitting these pins is simple: align the pin to the hole and press or tap it in evenly until seated. The component functions as a non-threaded retention element that resists axial forces in rotor systems and linkages. Keep extras for maintenance cycles and repairs.
