Hirobo HI2509015 Roll Pin 2 x 12 10pcs replacement roll pins for RC helicopter general parts  [HI2509015]

Roll pin for RC helicopters

The Hirobo HI2509015 roll pin 2 x 12 is supplied as a small-batch hardware pack of 10 pcs intended for use in RC-scale helicopters and other model airframes where a compact roll pin is required for axial retention.

Use cases include securing shafts, retaining small linkages, and locking components where a transverse pin is required. The 2 x 12 designation identifies the nominal diameter and length, which helps when selecting a replacement that fits existing pin holes without modifying surrounding parts.

Installation is straightforward: align the pin with the hole and press it evenly until seated; the part functions as a non-threaded retention element that resists axial movement in rotors and control linkages. For tuning and maintenance, keep spare pins on hand to restore original fit after wear or during rebuilds.
