Hirobo HI2509015 2 x 12 Roll Pin Set 10pcs for RC Helicopters  [HI2509015]

Compact retention pins for model rotors

The Hirobo HI2509015 roll pin 2 x 12 is supplied as a 10-piece hardware pack designed for RC helicopters and other model airframes where a compact roll pin is needed to provide axial retention.

Typical uses include securing small shafts, holding linkages in place, and locking components where a transverse pin is required. The 2 x 12 marking denotes the nominal diameter and length, which helps when choosing a direct replacement that fits existing holes without altering surrounding parts.

Fitting is simple: line the pin up with the hole and press or tap it in evenly until it seats; the pin acts as a non-threaded retention element that resists axial movement in rotors and control linkages. Carry spare pins to restore original fit after wear or during rebuilds.
